    Conclusions: There is limited evidence that physical behavioral techniques for PE improve IELT and other outcomes over waitlist and that behavioral therapies combined with drug treatments give better outcomes than drug treatments alone. Further RCTs are required to assess psychotherapeutic approaches to PE. Cooper K, Martyn‐St James M, Kaltenthaler E, Dickinson K, Cantrell A, Wylie K, Frodsham L, and Hood C.

    A cohort of extremely prematurely born children and matched term controls was assessed at 5 years of age. The parents completed a questionnaire on their behavioral and social development. The purpose was to illuminate whether the children's general intellectual ability and parental sensitivity were...... associated with behavioral and social development. The index children exhibited more hyperactive behavior and had poorer social skills than the controls. Lower Full Scale IQ (FSIQ) was associated with outward reacting and hyperactive behavior and poorer social skills. Sensitive parenting was associated...... with less outward reacting and less hyperactive behavior. When controlling for differences in FSIQ and parental sensitivity, the index children persisted to have an increased risk of exhibiting hyperactive behavior but not poorer social skills. The index children with normal intellectual development...

    Preterm birth can impact on child development. As seen previously, children born preterm present more behavioral and/or emotional problems than do full-term counterparts. In addition to gestational age, neonatal clinical status should be examined to better understand the differential impact of premature birth on later developmental outcomes. The aim of the present study was to systematically review empirical studies on the relationship between prematurity, neonatal health status, and behavioral and/or emotional problems in children. A systematic search of the PubMed, PsycINFO, Web of Science, and LILACS databases for articles published from 2009 to 2014 was performed. The inclusion criteria were empirical studies that evaluated behavioral and/or emotional problems that are related to clinical neonatal variables in children born preterm. Twenty-seven studies were reviewed. Results showed that the degree of prematurity and birth weight were associated with emotional and/or behavioral problems in children at different ages. Prematurity that was associated with neonatal clinical conditions (e.g., sepsis, bronchopulmonary dysplasia, and hemorrhage) and such treatments as corticoids and steroids increased the risk for these problems. The volume and abnormalities of specific brain structures also were associated with these outcomes. In conclusion, the neonatal health problems associated with prematurity present a negative impact on later child emotional and adapted behavior. © 2016 Michigan Association for Infant Mental Health.

    Full Text Available Background: Premature infants are among high-risk groups in community who need to be hospitalized at intensive care units for survival and receiving basic or special care. Hospitalization at neonatal intensive care units (NICUs unsettles the family and leads to the separation of parents from their infants. This study aimed to determine the effects of maternal attachment behaviors on the behavioral responses of premature infants, hospitalized at NICUs. Methods: In this randomized clinical trial, 64 premature infants, who were hospitalized at NICUs and were eligible for the study, were randomly allocated to study and control groups. Attachment behaviors including touching, massage and kangaroo care were applied for the study group, while the conventional attachment method was adopted for the control group. Behavioral responses were evaluated two hours before and two hours after training attachment behaviors. Data were analyzed, using Chi-square and student’s t-test. Results: The mean difference in the duration of deep sleep and consciousness was more significant in the study group, compared to the control group. Furthermore, the duration of drowsiness was significantly less in the study group, compared to the control group. Conclusion: The implementation of attachment training at NICUs decreased the time of drowsiness and improved behavioral responses, deep sleep time and consciousness.

    Sleep and ongoing cycling of sleep states are required for neurosensory processing, learning, and brain plasticity. Many aspects of neonatal intensive care environments such as handling for routine and invasive procedures, bright lighting, and noise can create stress, disrupt behavior, and interfere with sleep in prematurely born infants. The study empirically investigated whether a 30-minute observation of infant sleep states and behavior could differentiate an intervention to promote sleep in premature infants with feeding difficulties relative to conventional care (standard positioning, standard crib mattress [SP]). We included an intervention to determine the ability of the method to discriminate treatments and generate a benchmark for future improvements. The intervention, a conformational positioner (CP), is contoured around the infant to provide customized containment and boundaries. To more fully verify the 30-minute observational sleep results, standard polysomnography was conducted simultaneously and sleep outcomes for the 2 modalities were compared. In a randomized crossover clinical trial, 25 infants, 31.5 ± 0.6 weeks' gestational age and 38.4 ± 0.6 weeks at the study, with gastrointestinal conditions or general feeding difficulties used each intervention during an overnight neonatal intensive care unit sleep study. Infant sleep states and behaviors were observed during two 30-minute periods--that is, on the positioner and mattress--using the naturalistic observation of newborn behavior. Two certified developmental care nurses assessed sleep state, self-regulatory, and stress behaviors during 2-minute intervals and summed over 30 minutes. Sleep characteristics from standard polysomnography were measured at the time of behavior observations. Infants on CP spent significantly less time in alert, active awake, or crying states by observation compared with SP. Surgical subjects spent more time awake, active awake, or crying and displayed a higher number

    The intensity of behavioral and neuroendocrine responses to stressful stimuli in rodent strains seems to be inversely related to their life span. We have previously shown that interindividual differences in members of outbred Swiss and inbred BALB/c mouse populations, both male and female, may be related to their behavior in a simple T-maze test. The animals that explore the maze slowly show impaired neuromuscular vigor and coordination, decreased locomotor activity, increased level of emotionality/anxiety, decreased levels of brain biogenic amines as well as immunosenescence and decreased life span, when compared to their control counterparts, which quickly explore the maze. These traits are similar to some of the alterations previously observed in aging animals and therefore we proposed that those 'slow mice' are biologically older than the fast animals and may be a model of prematurely aging mice (PAM). Although most of our work on this model has been performed on chronologically adult-mature animals, we have also shown that certain characteristics of PAM, such as increased anxiety and deficient immune response, are already present in chronologically young animals. Thus, it is tempting to hypothesize that chronic hyperreactivity to stress (trait anxiety) leading to immune dysfunction may have a causal relationship with impaired health and premature aging. In view of the link between oxidative stress and the aging process, the redox state of peritoneal leukocytes from PAM has been studied, showing an oxidative stress situation. In the present work we have determined the levels of a key antioxidant, reduced glutathione (GSH), and the oxidant malondialdehyde (MDA), a marker of lipid peroxidation, both in the spleen and brain of male and female PAM and non-PAM (NPAM). We found that GSH and MDA are decreased and increased, respectively, in PAM with respect to NPAM. Moreover, diet supplementation with antioxidants showed to be an effective strategy for protection

    Full Text Available Iron is required for organismal growth. Therefore, limiting iron availability may be a key part of the host’s innate immune response to various pathogens, for example in Drosophila infected with Zygomycetes. One way the host can transiently reduce iron bioavailability is by ferritin overexpression. To study the effects of neuronal-specific ferritin overexpression on survival and neurodegeneration we generated flies simultaneously over-expressing transgenes for both ferritin subunits in all neurons. We used two independent recombinant chromosomes bearing UAS-Fer1HCH, UAS-Fer2LCH transgenes and obtained qualitatively different levels of late-onset behavioral and lifespan declines. We subsequently discovered that one parental strain had been infected with a virulent form of the bacterial endosymbiont Wolbachia, causing widespread neuronal apoptosis and premature death. This phenotype was exacerbated by ferritin overexpression and was curable by antibiotic treatment. Neuronal ferritin overexpression in uninfected flies did not cause evident neurodegeneration but resulted in a late-onset behavioral decline, as previously reported for ferritin overexpression in glia. The results suggest that ferritin overexpression in the central nervous system of flies is tolerated well in young individuals with adverse manifestations appearing only late in life or under unrelated pathophysiological conditions.

    The Social and Sensory Environment Studies of very low birthweight infants have quantified the amount and quality of social interaction with staff and parents and described the sound environment in an incubator. The present study concerns preterm infant behavior and reactions to these stimuli with particular reference to approach and withdrawal and vocalization. Among the findings are that while intermittent vocalization increases, infant cry decreases over the first three weeks in the incubator. Approach activities take place with some consistency whereas withdrawal differs from child to child. The ethnographic focus on interactive components of the intensive care experience documents the process of intersubjective development for the purpose of locating and isolating points of vulnerability in language and cognitive skills of infants born at very low birthweight.

  6. Type A behavior pattern is not a predictor of premature mortality.

    Type A personality was introduced in the 1950s and was defined as an action-emotion complex characterized by excessive competitive drive, intense striving for achievement, easily provoked hostility, aggressiveness, impatience, and exaggerated sense of time urgency. Despite many positive findings earlier, almost 50 years of studies have not yielded conclusive results regarding Type A as a risk factor for negative health outcomes and early death. This may partly be due to methodological weaknesses such as small and selected samples, short follow-up times, and varying ways to assess Type A across studies. We re-examined the association between the Type A concept with cardiovascular (CVD) and non-cardiovascular (non-CVD) mortality by using a long follow-up (on average 20.6 years) of a large population-based sample of elderly males (N = 2,682), by applying multiple Type A measures at baseline, and looking separately at early and later follow-up years. The study sample were the participants of the Kuopio Ischemic Heart Disease Risk Factor Study, (KIHD), which includes a randomly selected representative sample of Eastern Finnish men, aged 42-60 years at baseline in the 1980s. They were followed up until the end of 2011 through linkage with the National Death Registry. Four self-administered scales, Bortner Short Rating Scale, Framingham Type A Behavior Pattern Scale, Jenkins Activity Survey, and Finnish Type A Scale, were used for Type A assessment at the start of follow-up. Type A measures were inconsistently associated with cardiovascular mortality, and most associations were non-significant. Some scales suggested slightly decreased, rather than increased, risk of CVD death during the follow-up. Associations with non-cardiovascular deaths were even weaker. Our findings further suggest that there is no evidence to support the Type A as a risk factor for CVD and non-CVD mortality.

    1997-07-01

    Methods are presented for calculating component unavailabilities when inservice test (IST) intervals are changed and when component aging is explicitly included. The methods extend usual approaches for calculating unavailability and risk effects of changing IST intervals which utilize Probabilistic Risk Assessment (PRA) methods that do not explicitly include component aging. Different IST characteristics are handled including ISTs which are followed by corrective maintenances which completely renew or partially renew the component. ISTs which are not followed by maintenance activities needed to renew the component are also handled. Any downtime associated with IST, including the test downtime and the following maintenance downtime, is included in the unavailability evaluations. A range of component aging behaviors is studied including both linear and nonlinear aging behaviors. Based upon evaluations completed to date, pooled failure data on check valves show relatively small aging (e.g., less than 7% per year). However, data from some plant systems could be evidence for larger aging rates occurring in time periods less than 5 years. The methods are utilized in this report to carry out a range of sensitivity evaluations to evaluate aging effects for different possible applications. Based on the sensitivity evaluations, summary tables are constructed showing how optimal IST interval ranges for check valves can vary relative to different aging behaviors which might exist. The evaluations are also used to identify IST intervals for check valves which are robust to component aging effects. General insights on aging effects are also extracted. These sensitivity studies and extracted results provide useful information which can be supplemented or be updated with plant specific information. The models and results can also be input to PRAs to determine associated risk implications.

    It is apparent from this review that the lifestyle of an individual gravida can potentially lead to a premature delivery. Some of these adverse behavioral characteristics may be dealt with by education and motivation, and some with actual medical treatment. However, there also appears to be significant need for public policy reorientation if we are to make a significant impact on the problem of preterm delivery.

    Full Text Available Premature ejaculation (PE is a common male sexual disorder. Recent normative data suggests that men with an intravaginal ejaculatory latency time (IELT of less than 1 minute have "definite" PE, while men with IELTs between 1 and 1.5 minutes have "probable" PE. Although there is insufficient empirical evidence to identify the etiology of PE, there is limited correlational evidence to suggest that men with PE have high levels of sexual anxiety and inherited altered sensitivity of central 5-HT (5-hydroxytryptamine, serotonin receptors. Pharmacological modulation of the ejaculatory threshold using off-label daily or on-demand selective serotonin re-uptake inhibitors is well tolerated and offers patients a high likelihood of achieving improved ejaculatory control within a few days of initiating treatment, consequential improvements in sexual desire and other sexual domains. Investigational drugs such as the ejaculo-selective serotonin transport inhibitor, dapoxetine represent a major development in sexual medicine. These drugs offer patients the convenience of on-demand dosing, significant improvements in IELT, ejaculatory control and sexual satisfaction with minimal adverse effects.

  15. Enhancing the effectiveness of IST through risk-based techniques

    Floyd, S.D.

    1996-12-01

    Current IST requirements were developed mainly through deterministic-based methods. While this approach has resulted in an adequate level of safety and reliability for pumps and valves, insights from probabilistic safety assessments suggest a better safety focus can be achieved at lower costs. That is, some high safety impact pumps and valves are currently not tested under the IST program and should be added, while low safety impact valves could be tested at significantly greater intervals than allowed by the current IST program. The nuclear utility industry, through the Nuclear Energy Institute (NEI), has developed a draft guideline for applying risk-based techniques to focus testing on those pumps and valves with a high safety impact while reducing test frequencies on low safety impact pumps and valves. The guideline is being validated through an industry pilot application program that is being reviewed by the U.S. Nuclear Regulatory Commission. NEI and the ASME maintain a dialogue on the two groups` activities related to risk-based IST. The presenter will provide an overview of the NEI guideline, discuss the methodological approach for applying risk-based technology to IST and provide the status of the industry pilot plant effort.

    Full Text Available Qualitative Daten in den Sozial- und Wirtschaftswissenschaften müssen verstärkt verschiedenartigen Anforderungen gerecht werden. Förderinstitutionen fordern die langfristige Aufbewahrung von Primärdaten – entsprechend der Standards "guter wissenschaftlicher Praxis" sollen Forschungsdaten über das originäre Forschungsvorhaben hinaus verfügbar sein –, und internationale Fachzeitschriften erwarten vermehrt die Bereitstellung von Primärdaten, um Forschungsergebnisse für Dritte nachvollziehbar veröffentlichen zu können. Für eine digitale Archivierung und entsprechende Weitergabe qualitativer Interviewdaten, also personenbezogener Daten im Sinne der Datenschutzgesetze, lassen sich drei zentrale Probleme identifizieren: 1. Die Archivierung und Weitergabe von Forschungsprimärdaten ist an die Einwilligung der an der Studie teilnehmenden Personen gebunden. 2. Die Primärdaten sind zu anonymisieren, sobald der Forschungszweck dies ermöglicht. 3. Die aktuellen Datenschutzbestimmungen beinhalten eine Löschungspflicht für personenbezogene Daten, die im Widerspruch zu den Forderungen der Forschungsförderer und den Standards "guter wissenschaftlicher Praxis" steht. Genau an diesen Problemen setzt die vom Rat für Sozial- und Wirtschaftsdaten (RatSWD gegründete Arbeitsgruppe "Datenschutz und qualitative Sozialforschung" an. In der Arbeitsgruppe erarbeiten Fachvertreterinnen und Fachvertreter der qualitativen Sozialforschung gemeinsam mit Vertreterinnen und Vertretern der Rechtswissenschaften Empfehlungen zum praktischen Umgang mit qualitativen Interviewdaten.

    Full Text Available Na Universidade Estadual Paulista, Câmpus de Jaboticabal-SP, estudou-se o comportamento de Passifloráceas quanto à morte prematura de plantas, cultivadas em local com histórico da doença. O objetivo do trabalho foi avaliar o comportamento de diversos "acessos" de populações e espécies de maracujazeiros em relação a esta doença, sendo que as plantas resistentes deverão ser utilizadas como porta-enxertos de formas comerciais de maracujá-amarelo (Passiflora edulis Sims f. flavicarpa e em programas de melhoramento genético. As espécies utilizadas foram P. edulis Sims, P. edulis Sims f. flavicarpa Degener, P. nitida H.B.K., P. cincinnata, P. giberti, P. laurifolia, P. morifolia, P. foetida e P. capsularis. Em local com histórico da doença, plantaram-se mudas em número variável e em épocas distintas. A condução das plantas e os tratos culturais foram os recomendados para o maracujá-amarelo. A morte prematura das plantas ocorreu entre dois meses e dois anos da cultura no campo. P. giberti e P. nitida mostraram-se resistente à doença, independentemente do local de origem. Entre os demais "acessos", não se encontraram fontes promissoras de resistência. Entretanto, novos "acessos" e novas espécies deverão ser estudadas na busca da resistência.The behavior of passionfruit, cultivated in sites with disease history, as to premature death, was researched at Universidade Estadual Paulista, Campus of Jaboticabal, SP.

    2013-09-01

    Children born very preterm (≤ 32 weeks gestation) exhibit greater internalizing (anxious/depressed) behaviors compared to term-born peers as early as 2 years corrected age (CA); however, the role of early stress in the etiology of internalizing problems in preterm children remains unknown. Therefore, we examined the relationship between neonatal pain and internalizing behavior at 18 months CA in children born very preterm and examined whether parent behavior and stress moderated this relationship. Participants were 145 children (96 very preterm, 49 full term) assessed at 18 months CA. Neonatal data were obtained from medical and nursing chart review. Neonatal pain was defined as the number of skin-breaking procedures. Cognitive ability was measured with the Bayley Scales of Infant Development II. Parents completed the Parenting Stress Index III, Child Behavior Checklist 1.5-5, and participated in a videotaped play session with their child, which was coded using the Emotional Availability Scale IV. Very preterm children displayed greater Internalizing behaviors compared to full-term control children (P=.02). Parent Sensitivity and Nonhostility moderated the relationship between neonatal pain and Internalizing behavior (all Pneonatal medical confounders, gender, and child cognitive ability (all P>.05). Parent Emotional Availability and stress were not associated with Internalizing behaviors in full-term control children. Positive parent interaction and lower stress appears to ameliorate negative effects of neonatal pain on stress-sensitive behaviors in this vulnerable population.

  12. Risk-ranking IST components into two categories

    Energy Technology Data Exchange (ETDEWEB)

    Rowley, C.W.

    1996-12-01

    The ASME has utilized several schemes for identifying the appropriate scope of components for inservice testing (IST). The initial scope was ASME Code Class 1/2/3, with all components treated equally. Later the ASME Operations and Maintenance (O&M) Committee decided to use safe shutdown and accident mitigation as the scoping criteria, but continued to treat all components equal inside that scope. Recently the ASME O&M Committee decided to recognize service condition of the component, hence the comprehensive pump test. Although probabilistic risk assessments (PRAs) are incredibly complex plant models and computer hardware and software intensive, they are a tool that can be utilized by many plant engineering organizations to analyze plant system and component applications. In 1992 the ASME O&M Committee got interested in using the PRA as a tool to categorize its pumps and valves. In 1994 the ASME O&M Committee commissioned the ASME Center for Research and Technology Development (CRTD) to develop a process that adapted the PRA technology to IST. In late 1995 that process was presented to the ASME O&M Committee. The process had three distinct portions: (1) risk-rank the IST components; (2) develop a more effective testing strategy for More Safety Significant Components; and (3) develop a more economic testing strategy for Less Safety Significant Components.

    Premature birth is a significant cause of infant and child morbidity and mortality. In the United States, the premature birth rate, which had steadily increased during the 1990s and early 2000s, has decreased annually for four years and is now approximately 11.5%. Human viability, defined as gestational age at which the chance of survival is 50%, is currently approximately 23–24 weeks in developed countries. Infant girls, on average, have better outcomes than infant boys. A relatively uncomplicated course in the intensive care nursery for an extremely premature infant results in a discharge date close to the prenatal EDC. Despite technological advances and efforts of child health experts during the last generation, the extremely premature infant (less than 28 weeks gestation) and extremely low birth weight infant (ELBW) (premature labor improved neonatal mortality and morbidity in the late 1990s. The recognition that chronic postnatal administration of steroids to infants should be avoided may have improved outcomes in the early 2000s. Evidence from recent trials attempting to define the appropriate target for oxygen saturation in preterm infants suggests arterial oxygen saturation between 91–95% (compared to 85–89%) avoids excess mortality. However, final analyses of data from these trials have not been published, so definitive recommendations are still pending The development of neonatal neurocognitive care visits may improve neurocognitive outcomes in this high-risk group. Long-term follow up to detect and address developmental, learning, behavioral, and social problems is critical for children born at these early gestational ages. The striking similarities in response to extreme prematurity in the lung and brain imply that agents and techniques that benefit one organ are likely to also benefit the other. Finally, since therapy and supportive care continue to change, the outcomes of ELBW infants are ever evolving. Efforts to minimize injury, preserve

    Premature birth is a significant cause of infant and child morbidity and mortality. In the United States, the premature birth rate, which had steadily increased during the 1990s and early 2000s, has decreased annually for 7 years and is now approximately 11.39%. Human viability, defined as gestational age at which the chance of survival is 50%, is currently approximately 23 to 24 weeks in developed countries. Infant girls, on average, have better outcomes than infant boys. A relatively uncomplicated course in the intensive care nursery for an extremely premature infant results in a discharge date close to the prenatal estimated date of confinement. Despite technological advances and efforts of child health experts during the last generation, the extremely premature infant (less than 28 weeks gestation) and extremely low birth weight infant (death and disability with 30% to 50% mortality and, in survivors, at least 20% to 50% risk of morbidity. The introduction of continuous positive airway pressure, mechanical ventilation, and exogenous surfactant increased survival and spurred the development of neonatal intensive care in the 1970s through the early 1990s. Routine administration of antenatal steroids during premature labor improved neonatal mortality and morbidity in the late 1990s. The recognition that chronic postnatal administration of steroids to infants should be avoided may have improved outcomes in the early 2000s. Evidence from recent trials attempting to define the appropriate target for oxygen saturation in preterm infants suggests arterial oxygen saturation between 91% and 95% (compared with 85%-89%) avoids excess mortality; however, final analyses of data from these trials have not been published, so definitive recommendations are still pending.

    Background: Invasive fungal infections cause excessive morbidity and mortality in premature neonates and severely ill infants. Methods: Safety and efficacy outcomes of micafungin were compared between prematurely and non-prematurely born infants premature [birth weight (BW) premature, received ≥1 dose of micafungin. Among premature patients, 14.5% were low BW (1500–2499 g), 36.4% very low BW (1000–1499 g) and 49.1% extremely low BW (premature)] died. Significantly more non-premature than premature patients discontinued treatment (P = 0.003). Treatment-related adverse events were recorded in 23% of patients with no difference between groups. More extremely low BW (n = 4, 15%) and very low BW (n = 8, 40%) infants experienced treatment-related adverse events than low BW (n = 0) and there was no relation to micafungin dose or duration. For a subgroup of 30 patients with invasive candidiasis, treatment success was achieved in 73% in both premature and non-premature groups. Prophylaxis was successful in 4/5 non-premature hematopoietic stem cell transplant patients. Conclusion: Micafungin has a safe profile in premature and non-premature infants with substantial efficacy. PMID:24892849

    Full Text Available Nach der Printausgabe der „Enzyklopädie des Nationalsozialismus“, die 1998 im Klett-Verlag erschien, liegt nun unter dem gleichnamigen Titel eine CD-ROM in der Digitalen Bibliothek des Verlages Directmedia Publishing vor. Angekündigt ist sie als umfassendes Nachschlagewerk zum Nationalsozialismus, im Aufbau als eine Kombination aus Handbuch, Sachlexikon und kommentiertem Personenverzeichnis. Bei diesem Anspruch darf erwartet werden, daß die Herausgeber dieses Werkes auch die Geschlechterperspektive berücksichtigen. Da kein Bereich sozialen Handelns und gesellschaftlicher Praxis unabhängig von Geschlechterdifferenzen strukturiert ist, ist es für die Erforschung historischer, politischer, kultureller Quellen unabdingbar, die Kategorie Geschlecht mit in den Blick zu nehmen, um so das Ineinander und Gegeneinander geschlechtsspezifischer Verhaltensweisen von Männern und Frauen sichtbar zu machen.Following the printed version issued by Klett in 1998, the “Encyclopedia of National Socialism” ist now also available on CD-ROM in the digital library of the Directmedia Publishing group. It is advertised as being a comprehensive reference work on National Socialism, structurally a combination of manual, encyclopedia and annotated register of persons. Considering these high standards it is to be expected that the editors would take the existence of different gender perspectives into account. There is no sphere of social action and practice which could claim to be structurally independent of gender differences; therefore, when researching historical, political or cultural sources, it is indispensable to be mindful of the category gender to make the interacting behavioral patterns specific to men and women as transparent as possible.

    Massage therapy has been used in the care of premature infants for many years in western countries, and a significant body of research has already shown the effectiveness of massage therapy in significantly increasing body weight, decreasing infant hospital durations, enhancing bone formation, and improving behavior. Key considerations when applying massage therapy on premature infants include gestational age, bodyweight, and physical condition. Nurses can teach parents to administer massage therapy on their premature infants to enhance parent-child attachment and interaction. This article introduces massage therapy principles and methods, the effectiveness of massage therapy in premature infant care, and an approach to teaching parents how to apply massage therapy on their premature infants. Massage therapy can be included in premature infant care programs in the future.

    Premature infants are thought to be at increased risk for developmental disorders. We evaluated facial recognition by premature infants during early infancy, as this ability has been reported to be impaired commonly in developmentally disabled children. In premature infants and full-term infants at the age of 4 months (4 corrected months for premature infants), visual behaviors while performing facial recognition tasks were determined and analyzed using an eye-tracking system (Tobii T60 manufactured by Tobii Technologics, Sweden). Both types of infants had a preference towards normal facial expressions; however, no preference towards the upper face was observed in premature infants. Our study suggests that facial recognition ability in premature infants may develop differently from that in full-term infants.

  20. Premature Ejaculation and Utilization of Cognitive Techniques

    2013-03-01

    Full Text Available Introduction: Premature ejaculation is the most common male sexual dysfunction leading to distress in many couples. Master and Johnson emphasized the concept of early learned experiences and Kaplan emphasized lack of sensory awareness. For treatment sex therapists mainly utilize start-stop and squeeze techniques as homework. Couples enter sex therapy with some cognitive distortions and beliefs about sex and sexuality. These beliefs are also named sexual myths. For some couples using techniques to challenge cognitive distortions and maladaptive beliefs about sex and sexuality can be used. In this paper by presenting a case we discussed how cognitive techniques can be used along with behaviour techniques with couples. Case: Presenting clients are five years married couple who are thirty and twenty nine years old respectively. They attended to the outpatient clinic with the request of the female client. Their main complaint was premature ejaculation. They were diagnosed premature ejaculation using clinical interview. In treatment besides start and stop technique, cognitive techniques were utilized to address dysfunctional beliefs about sexuality. Discussion: Premature ejaculation is a male sexual dysfunction that causes distress and intimacy problems between couples. Stop start and squeeze techniques were accepted as the choice of treatment but their effectiveness is questioned recently. Also cognitive distortions and maladaptive beliefs may hamper therapy progress. Besides that, behavioral techniques utilizing cognitive techniques to lessen the degree of dysfunctional beliefs about sex and sexuality may help the couple to overcome premature ejaculation and enhance sexual satisfaction and intimacy.

    Caffeine citrate therapy for apnea of prematurity reduces the rates of bronchopulmonary dysplasia, severe retinopathy, and neurodevelopmental disability at 18 months and may improve motor function at 5 years. To evaluate whether neonatal caffeine therapy is associated with improved functional outcomes 11 years later. A follow-up study was conducted at 14 academic hospitals in Canada, Australia, and the United Kingdom from May 7, 2011, to May 27, 2016, of English- or French-speaking children who had been enrolled in the randomized, placebo-controlled Caffeine for Apnea of Prematurity trial between October 11, 1999, and October 22, 2004. A total of 1202 children with birth weights of 500 to 1250 g were eligible for this study; 920 (76.5%) had adequate data for the main outcome. Caffeine citrate or placebo until drug therapy for apnea of prematurity was no longer needed. Functional impairment was a composite of poor academic performance (defined as at least 1 standard score greater than 2 SD below the mean on the Wide Range Achievement Test-4), motor impairment (defined as a percentile rank of ≤5 on the Movement Assessment Battery for Children-Second Edition), and behavior problems (defined as a Total Problem T score ≥2 SD above the mean on the Child Behavior Checklist). Among the 920 children (444 females and 476 males; median age, 11.4 years [interquartile range, 11.1-11.8 years]), the combined rates of functional impairment were not significantly different between the 457 children assigned to receive caffeine compared with the 463 children assigned to receive placebo (145 [31.7%] vs 174 [37.6%]; adjusted odds ratio, 0.78; 95% CI, 0.59-1.02; P = .07).

    At River Bend Station, IST testing had problems. Operations could not perform the test with the required repeatability; engineering could not reliably trend test data to detect degradation; licensing was heavily burdened with regulatory concerns; and maintenance could not do preventative maintenance because of poor prediction of system health status. Using Energy`s Total Quality principles, it was determined that the causes were: lack of ownership, inadequate test equipment usage, lack of adequate procedures, and lack of program maintenance. After identifying the customers and suppliers of the IST program data, Energy management put together an upgrade team to address these concerns. These customers and suppliers made up the IST upgrade team. The team`s mission was to supply River Bend with a reliable, functional, industry correct and user friendly IST program. The IST program in place went through a verification process that identified and corrected over 400 individual program discrepancies. Over 200 components were identified for improved testing methods. An IST basis document was developed. The operations department was trained on ASME Section XI testing. All IST tests have been simplified and shortened, due to heavy involvement by operations in the procedure development process. This significantly reduced testing time, resulting in lower cost, less dose and greater system availability.

    Premature ejaculation is the most common form of sexual dysfunction among men. The pathophysiology of premature ejaculation appears to be multifactorial, implicating the need for multimodal therapeutic regimens to successfully treat premature ejaculation. Multiple treatment regimens have been shown to be effective in extending the time between penetration and ejaculation. These treatment modalities include everything from behavioral modifications and medications to diet alterations and major surgery. The goal of the present article was to review the commonly used treatment regimens used in the treatment of premature ejaculation, as well as to introduce and discuss the newest treatment routines under study for the treatment of premature ejaculation.

    Full Text Available The membranes surrounding the amniotic cavity are composed from amnion and chorion, tightly adherent layers which are composed of several cell types, including epithelial cells, trophoblasts cells and mesenchyme cells, embedded in a collagenous matrix. They retain amniotic fluid, secret substances into the amniotic fluid, as well as to the uterus and protect the fetus against upward infections from urogenital tract. Normally, the membranes it breaks during labor. Premature rupture of the amniotic sac (PRAS is defined as rupture of membranes before the onset of labor. Premature rupture of the fetal membrane, which occurs before 37 weeks of gestation, usually, refers to preterm premature rupture of membranes. Despite advances in the care period, premature rupture of membranes and premature rupture of membranes preterm continue to be regarded as serious obstetric complications. On the term 8% - 10% of pregnant women have premature rupture of membranes; these women are at increased risk of intrauterine infections, where the interval between membrane rupture and expulsion is rolled-over. Premature rupture of membranes preterm occurs in approximately 1% of all pregnancies and is associated with 30% -40% of preterm births. Thus, it is important to identify the cause of pre-term birth (after less than 37 completed weeks of "gestation" and its complications, including respiratory distress syndrome, neonatal infection and intraventricular hemorrhage. Objectives: the development of the protocol of the clinical trial on patients with impending preterm birth, study clinical and statistical on the socio-demographic characteristics of patients with imminent preterm birth; clinical condition of patients and selection of cases that could benefit from the application of interventional therapy; preclinical investigation (biological and imaging of patients with imminent preterm birth; the modality therapy; clinical investigation of the effectiveness of short

    2010-11-01

    Premature ovarian failure (POF) is a common cause of infertility in women, and is characterised by amenorrhoea, hypo-oestrogenism and elevated gonadotrophin levels in women under the age of 40. Known causes include iatrogenic agents that cause permanent damage to the ovaries, such as chemotherapy, radiation therapy and surgery, autoimmune conditions, X-chromosome abnormalities and autosomal genetic conditions. However, few genes have been identified that can explain a substantial proportion of cases of POF. Most women with POF are deeply upset by the diagnosis, partly due to the unexpected menopausal symptoms, but also due to infertility. Therefore, early detection would provide better opportunity for early intervention, and furthermore, the identification of specific gene defects will help to direct potential targets for future treatment.

    Full Text Available Apnea of prematurity (AOP is one of the most frequent pathologies in the Neonatal Intensive Care Unit, with an incidence inversely related to gestational age. Its etiology is often multi factorial and diagnosis of idiopathic forms requires exclusion of other underlying diseases. Despite being a self-limiting condition which regresses with the maturation of the newborn, possible long-term effects of recurring apneas and the degree of desaturation and bradycardia who may lead to abnormal neurological outcome are not yet clarified. Therefore AOP needs careful evaluation of its etiology and adequate therapy that can be both pharmacological and non-pharmacological. Proceedings of the 9th International Workshop on Neonatology · Cagliari (Italy · October 23rd-26th, 2013 · Learned lessons, changing practice and cutting-edge research

    Full Text Available Premature ejaculation (PE is a common male sexual disorder. It is defined by the Diagnostic and statistical manual of mental disorders as "ejaculation occurring, without control, on or shortly after penetration and before the person wishes it, causing marked distress or interpersonal difficulty. [1] Although the timing of intravaginal ejaculatory latency time (IELT (i.e., time from penetration to ejaculation is not included in this definition, an IELT of <2 min, or ejaculation occurring before penetration, has been considered consistent with PE. [2] Management involves both the patient and his partner. Therapeutic options should suit both partners and be appropriate to their habit in planning and frequency of intercourse. Follow-up at appropriate intervals to judge efficacy, titrate dosage of pharmacological treatments and ascertain side effects is mandatory.

    2002-01-01

    Intrauterine infection is a major cause of premature labor with and without intact membranes. Intrauterine infection is present in approximately 25% of all preterm births and the earlier the gestational age at delivery, the higher the frequency of intra-amniotic infection. Microorganisms may also gain access to the fetus before delivery. A fetal inflammatory response syndrome elicited in response to microbial products is associated with the impending onset of preterm labor and also with multi-systemic organ involvement in the human fetus and a higher rate of perinatal morbidity. The most common microorganisms involved in intrauterine infections are Ureaplasma urealyticum, Fusobacterium species and Mycoplasma hominis. The role of Chlamydia trachomatis and viruses in preterm labor remain to be determined. Use of molecular microbiology techniques to diagnose intrauterine infection may uncover the role of fastidious microorganisms that have not yet been discovered. Antibiotic administration to patients with asymptomatic bacteriuria is associated with a significant reduction in the rate of preterm birth. However, such benefit has not been demonstrated for patients with bacterial vaginosis, or women who carry Streptococcus agalactia, Ureaplasma urealyticum or Trichomonas vaginalis. Antibiotic administration to patients with preterm premature rupture of membranes is associated with prolongation of pregnancy and a reduction in the rate of clinical chorioamnionitis and neonatal sepsis. The benefit has not been demonstrated in patients with preterm labor and intact membranes. Major efforts are required to determine why some women develop an ascending intrauterine infection and others do not and also what interventions may reduce the deleterious effect of systemic fetal inflammation.

    McCormick, Marie C; Litt, Jonathan S; Smith, Vincent C; Zupancic, John A F

    2011-01-01

    The high rate of premature births in the United States remains a public health concern. These infants experience substantial morbidity and mortality in the newborn period, which translate into significant medical costs. In early childhood, survivors are characterized by a variety of health problems, including motor delay and/or cerebral palsy, lower IQs, behavior problems, and respiratory illness, especially asthma. Many experience difficulty with school work, lower health-related quality of life, and family stress. Emerging information in adolescence and young adulthood paints a more optimistic picture, with persistence of many problems but with better adaptation and more positive expectations by the young adults. Few opportunities for prevention have been identified; therefore, public health approaches to prematurity include assurance of delivery in a facility capable of managing neonatal complications, quality improvement to minimize interinstitutional variations, early developmental support for such infants, and attention to related family health issues.

  18. Psychosocial interventions for premature ejaculation

    Tamara Melnik

    Full Text Available BACKGROUND: Premature ejaculation (PE is a very common sexual dysfunction among patients, and with varying prevalence estimates ranging from 3% to 20%. Although psychological issues are present in most patients with premature PE, as a cause or as a consequence, research on the effects of psychological approaches for PE has in general not been controlled or randomised and is lacking in long-term follow up. OBJECTIVE: To assess the efficacy of psychosocial interventions for PE. CRITERIA FOR CONSIDERING STUDIES FOR THIS REVIEW: Trials were searched in computerized general and specialized databases, such as: MEDLINE by PubMed (1966 to 2010; PsycINFO (1974 to 2010; EMBASE (1980 to 2010; LILACS (1982 to 2010; the Cochrane Central Register of Controlled Trials (Cochrane Library, 2010; and by checking bibliographies, and contacting manufacturers and researchers. SELECTION CRITERIA: Randomised or quasi-randomised controlled trials evaluating psychosocial interventions compared with different psychosocial interventions, pharmacological interventions, waiting list, or no treatment for PE. DATA COLLECTION AND ANALYSIS: Information on patients, interventions, and outcomes was extracted by at least two independent reviewers using a standard form. The primary outcome measure for comparing the effects of psychosocial interventions to waiting list and standard medications was improvement in IELT (i.e., time from vaginal penetration to ejaculation. The secondary outcome was change in validated PE questionnaires. MAIN RESULTS: In one study behavioral therapy (BT was significantly better than waiting list for duration of intercourse (MD (mean difference 407.90 seconds, 95% CI 302.42 to 513.38, and couples' sexual satisfaction (MD -26.10, CI -50.48 to -1.72. BT was also significantly better for a new functional-sexological treatment (FS (MD 412.00 seconds, 95% CI 305.88 to 518.12, change over time in subjective perception of duration of intercourse (Women: MD 2

Methods Premature infants were given different nutritional feeding, 65 selected subjects were divided into A group (high protein group, the average daily intake of protein ≥ 3g/kg.d), B group (usual protein, the daily intake of protein <3g/kg.d), and was corrected gestational age after 37 weeks, 40 weeks and 7 days, 14days, 28 days with NBNA score. Results With the growing age after birth, two sets of NBNA scores were gradually increased; NBNA scores at 5 time points of A group were higher than those in B group, the difference was statistically significant (P<0.05); two groups had the fastest growth rate while corrected gestational age at 37-40 weeks when, but growth slowed down after the increase with age. Conclusion Early feeding with high protein content to preterm infants can promote their neurobehavioral development, helps to reduce neurological sequelae, and promote its growth.

  20. Prenatal Stress, Prematurity, and Asthma.

    2015-12-01

    Asthma is the most common chronic disease of childhood, affecting millions of children in the United States and worldwide. Prematurity is a risk factor for asthma, and certain ethnic or racial minorities such as Puerto Ricans and non-Hispanic blacks are disproportionately affected by both prematurity and asthma. In this review, we examine current evidence to support maternal psychosocial stress as a putative link between prematurity and asthma, while also focusing on disruption of the hypothalamic-pituitary-adrenal (HPA) axis and immune responses as potential underlying mechanisms for stress-induced "premature asthma." Prenatal stress may cause not only abnormalities in the HPA axis but also epigenetic changes in the fetal glucocorticoid receptor gene (NR3C1), leading to impaired glucocorticoid metabolism. Moreover, maternal stress can alter fetal cytokine balance, favoring TH2 (allergic) immune responses characteristic of atopic asthma: interleukin 6 (IL-6), which has been associated with premature labor, can promote TH2 responses by stimulating production of IL-4 and IL-13. Given a link among stress, prematurity, and asthma, future research should include birth cohorts aimed at confirming and better characterizing "premature asthma." If confirmed, clinical trials of prenatal maternal stress reduction would be warranted to reduce the burden of these common comorbidities. While awaiting the results of such studies, sound policies to prevent domestic and community violence (eg, from firearms) are justified, not only by public safety but also by growing evidence of detrimental effects of violence-induced stress on psychiatric and somatic health.

  1. Premature ovarian failure

    2012-01-01

    Full Text Available Premature ovarian failure (POF is the occurrence of hypergonadotropic hypoestrogenic amenorrhea in women under the age of forty years. It is idiopathic in 74-90% patients. Known cases can be divided into primary and secondary POF. In primary POF genetic aberrations can involve the X chromosome (monosomy, trisomy, translocations, deletions or autosomes. Genetic mechanisms include reduced gene dosage and non-specific chromosome effects impairing meiosis, decreasing the pool of primordial follicles and increasing atresia due to apoptosis or failure of follicle maturation. Autoimmune ovarian damage is caused by alteration of T-cell subsets and T-cell mediated injury, increase of autoantibody producing B-cells, a low number of effector/cytotoxic lymphocyte, which decreases the number and activity of natural killer cells. Bilateral oophorectomy, chemotherapy, radiotherapy and infections cause the secondary POF. Symptoms of POF include irritability, nervousness, loss of libido, depression, lack of concentration, hot flushes, weight gaining, dry skin, vaginal dryness, frequent infections etc. The diagnosis is confirmed by the level of FSH of over 40 IU/L and estradiol below 50 pmol/L in women aged below 40 years. Biochemical and other hormonal analysis (free thyroxin, TSH, prolactin, testosterone, karyotype (<30 years of age, ultrasound of the breasts and pelvis are advisable. Optimal therapy is combined estrogen progestagen therapy given in a sequential rhythm, after excluding absolute contraindications. Testosterone can be added to adnexectomized women and those with a low libido. Sequential estrogen progestagen replacement therapy is the first line therapy for ovulation induction in those looking for pregnancy and after that oocyte donation will be advised. Appropriate estro-progestagen therapy improves the quality of life and prevents complications such as cardiovascular diseases, osteoporosis, stroke etc.

    Premature ejaculation (PE) is recognized to be the most common male sexual disorder. PE provides difficulties for professionals who treat this condition because there is neither a universally accepted definition nor a medication approved by the Food and Drug Administration (FDA). Despite these shortcomings, physicians continue to diagnose their patients with PE according to major guidelines and treat them with either behavioral therapies or off-label medications. This review focuses on current and emerging treatment options and medications for PE. Advantages and limitations of each treatment option are discussed in the light of current published peer-reviewed literature.

    Manual curation of biomedical literature has become extremely tedious process due to its exponential growth in recent years. To extract meaningful information from such large and unstructured text, newer and more efficient mining tool is required. Here, we introduce PALM-IST, a computational platform that not only allows users to explore biomedical abstracts using keyword based text mining but also extracts biological entity (e.g., gene/protein, drug, disease, biological processes, cellular component, etc.) information from the extracted text and subsequently mines various databases to provide their comprehensive inter-relation (e.g., interaction, expression, etc.). PALM-IST constructs protein interaction network and pathway information data relevant to the text search using multiple data mining tools and assembles them to create a meta-interaction network. It also analyzes scientific collaboration by extraction and creation of “co-authorship network,” for a given search context. Hence, this useful combination of literature and data mining provided in PALM-IST can be used to extract novel protein-protein interaction (PPI), to generate meta-pathways and further to identify key crosstalk and bottleneck proteins. PALM-IST is available at www.hpppi.iicb.res.in/ctm. PMID:25989388

    To longitudinally assess stability and correlates of prematurity stereotyping and perceptions of infant vulnerability in mothers of premature (N = 56) and full-term (N = 59) infants. At 5, 9, and 12 months, mothers rated videotapes of unfamiliar infants with a full-term label (FTL) or a preterm label (PL), interacted with their own infant, and completed other questionnaires. A subgroup of infants were administered a developmental assessment at 32 months. Mothers rated PL infants more negatively than FTL infants at each age. Individual differences in stereotyping were not stable. Mothers who negatively rated infants labeled with the same birth status of their own infants exhibited more negative interactive behaviors with their infants. Mothers who viewed their own infant as more vulnerable and who showed more prematurity stereotyping at 5 months had infants with lower 32-month mental scores. The results suggest an association between early maternal cognitions and both contemporaneous maternal behavior and later child developmental outcomes.

  15. Was ist eine Frau? Sexualität, Begehren und Einschreiben

    2016-07-01

    Full Text Available Da die menschliche Sexualität nicht natürlich ist, reichen anatomische oder biologische Argumente nicht, um sie aufzuklären. Freud entdeckte, dass der Geschlechtsunterschied durch den Signifikanten vermittelt wird, denn Triebe als solche ignorieren die Dichotomie Mann/Frau. Jacques Lacan greift diesen vernachlässigten Aspekt auf und hebt die Schicksale des Subjekts mit der Sprache durch seine Lehre als etwas Fundamentales hervor. In Anbetracht der Prämisse, dass «die Neurose wie eine Frage strukturiert» sei, drücken die komplexen symptomatischen Manifestationen der Hysterika ihren Versuch aus, sich in einen Diskurs einzuschreiben, der von der Unmöglichkeit, eine kategoriale Antwort auf das Rätsel der Weiblichkeit zu geben, geprägt ist. Deren Frage lautet also: Was ist eine Frau? Ein Signifikant ergibt nur Sinn in Verbindung zu einem anderen Signifikanten und daher werden wir alle den durch den Signifikanten vermittelten Sachen gegenüber unabänderlich entfremdet. Aus dieser Sichtweise heraus möchte ich mich mit der Frage der Heterosexualität auseinandersetzen.

    We describe a system architecture aimed at supporting Intelligence, Surveillance, and Reconnaissance (ISR) activities in a Company Intelligence Support Team (CoIST) using natural language-based knowledge representation and reasoning, and semantic matching of mission tasks to ISR assets. We illustrate an application of the architecture using a High Value Target (HVT) surveillance scenario which demonstrates semi-automated matching and assignment of appropriate ISR assets based on information coming in from existing sensors and human patrols operating in an area of interest and encountering a potential HVT vehicle. We highlight a number of key components of the system but focus mainly on the human/machine conversational interaction involving soldiers on the field providing input in natural language via spoken voice to a mobile device, which is then processed to machine-processable Controlled Natural Language (CNL) and confirmed with the soldier. The system also supports CoIST analysts obtaining real-time situation awareness on the unfolding events through fused CNL information via tools available at the Command and Control (C2). The system demonstrates various modes of operation including: automatic task assignment following inference of new high-importance information, as well as semi-automatic processing, providing the CoIST analyst with situation awareness information relevant to the area of operation.

    Full Text Available Background and Objectives: There are studies that support music and singing as appropriate developmental care for premature infants, thus, we conducted this study to investigate the physiological and behavioral responses of premature infants to Quran recitation, lullaby music and silence. Methods: In a randomized controlled trial (2011-2012,120 premature infants in the Neonatal Unit (NNU at Izadi Hospital, were randomly assigned to experimental (holy Quran recitation, lullaby music and silence and control groups. The four groups were surveyed for physiological responses including, oxygen saturation, respiratory rate and heart rate and behavioral states. The data were analyzed using SPSS-PC software and quantitative tests. Results: 66females and 54 male infants with gestational age 28- 36 weeks entered into the study. The fourgroupswere not significantly different in terms of demographic variables (P>0.05. The comparisonofchangesinthe infant’s responsesintheendof the intervention comparedtothebase lines, showedno statistically significant differencesbetweengroups(P>0.05. Repeated measures ANOVA and Friedman test did notindicate any significant differences in the mean ofresponseswithinanyof the four groups during the courseof study (P>0.05. Conclusion: Although fluctuations were observed in the mean of physiological responses and behavioral states in premature infants who listened to the recitation of the holy Quran and lullaby music, but these fluctuations were not significant. Findings of this study demonstrated that the preterm infants did not display any adverse reactions to the carefully designed acoustic intervention.

    2015-02-01

    Full Text Available The aim was to describe current reports in the scientific literature on sleep in the intensive care environment and sleep deprivation associated with painful experiences in premature infant. A systematic search was conducted for studies on sleep, pain, premature birth and care of the newborn. Web of Knowledge, MEDLINE, LILACS, Cochrane Library, PubMed, EMBASE, Scopus, VHL and SciELO databases were consulted. The association between sleep deprivation and pain generates effects that are observed in the brain and the behavioral and physiological activity of preterm infants. Polysomnography in intensive care units and pain management in neonates allow comparison with the first year of life and term infants. We have found few references and evidence that neonatal care programs can influence sleep development and reduce the negative impact of the environment. This evidence is discussed from the perspective of how hospital intervention can improve the development of premature infants.

  4. Animal models of premature and retarded ejaculation.

    2005-06-01

    Most of our current understanding of the neurobiology of sexual behavior and ejaculatory function has been derived from animal studies using rats with normal sexual behaviour. However, none of these proposed models adequately represents human ejaculatory disorders. Based on the "ejaculation distribution theory", which postulates that the intravaginal ejaculation latency time in men is represented by a biological continuum, we have developed an animal model for the research of premature and delayed ejaculation. In this model, a large number of male Wistar rats are investigated during 4-6 weekly sexual behavioural tests. Based on the number of ejaculations during 30 min tests, rapid and sluggish ejaculating rats are distinguished, each representing approximately 10% at both ends of a Gaussian distribution. Together with other parameters, such as ejaculation latency time, these rats at either side of the spectrum resemble men with premature and delayed ejaculation, respectively. Comparable to the human situation, in a normal population of rats, endophenotypes exist with regard to basal sexual (ejaculatory) performance.

    In this paper, we report on the structural, vibrational and magnetic behavior of Ist group elements (Li{sup +}, Na{sup +} and K{sup +}) codoping effect in ZnO:Fe nanoparticles (NPs) prepared by co-precipitation method. The single crystalline phase of the prepared NPs was identified as Wurtizite structure and the Raman spectra expressed the local structural change and the presence of complex lattice defects such as Zinc interstitial (Zn{sub i}) and Oxygen vacanvy (V{sup +}{sub o}) defects in the NPs. The presence of functional groups was confirmed by FT-IR spectral analysis. The optical absorption properties of the prepared NPs were characterised by UV-Drs spectroscopy. The valance state of Zinc ions and the role of Oxygen related defects were analysed from x-ray photoelectron spectroscopy (XPS) spectra. The electron paramagnetic resonance (EPR) spectral line illustrated the presence of complex defects such as Zinc interstitial (Zn{sub i}) and oxygen vacancy (V{sup +}{sub o}) defects in the sample. The observed room temperature ferromagnetism (RTFM) in the prepared sample was induced by lattice defects. The observed results are discussed and reported.

    Full Text Available Zielsetzung: Der im Genitalbereich und unteren Harntrakt lokalisierte Schmerz ist ein häufiges Symptom in der urologischen Praxis. Unbefriedigende Therapieansätze und langjährige ungenügende Behandlungserfolge für den Patienten charakterisieren diese Problematik. Die folgende Arbeit umfaßt eine Analyse klinischer und urodynamischer Befunde bei Patienten mit chronischen Beckenschmerzen, um die Arbeitshypothese eines Zusammenhanges zwischen Beckenschmerzen und funktionellen Störungen des unteren Harntraktes zu belegen oder auszuschließen. Material und Methode: Eine retrospektive Auswertung von Anamnese, klinischer und urodynamischer Untersuchung wurde bei 103 Männern (durchschnittliches Alter 47, von 23 bis 89 Jahren mit Beckenbeschwerden von 8/1994 bis 8/1997 durchgeführt. Alle in die Untersuchung eingeschlossenen Patienten hatten mehrere verschiedene konservative Therapieansätze ohne Erfolg hinter sich. Ergebnisse: Die Hauptlokalisationen des Schmerzes waren: Prostata/Perineum 45,6 %, Scrotum/Hoden 38,8 %, Penis 5,8 %, Harnblase 5,8 %, Unterbauch 1,9 %, Rücken 1,9 %. Eine deutliche Beckenbodendysfunktion war bei 88,3 % der Patienten reproduzierbar nachweisbar. Bei 84 Patienten wurde eine urodynamische Untersuchung durchgeführt. Hauptbefunde waren: 1 eine Zunahme des Sphinktertonus, 2 eine Reduktion des maximalen Harnflusses, 3 eine Verlängerung der funktionellen Urethralänge. Diskussion: Der Zusammenhang zwischen Beckenbodendysfunktion und Beckenschmerz ist offensichtlich. Was hierbei Ursache oder Folge ist und inwieweit diese Störungen auf einer primären oder sekundären Funktionsstörung des ZNS beruhen, kann derzeit nicht abschließend bewertet werden. Allerdings belegen Erfolge therapeutischer Maßnahmen, die am Beckenboden angreifen (Biofeedback, Alpha-Blockade, sakrale Neuromodulation die Hypothese eines Zusammenhanges zwischen Funktionsstörung und Beckenschmerzen.

    Directory of Open Access Journals (Sweden)

    Lerchbaum E

    2014-01-01

    Full Text Available Neben der klassischen Rolle von Vitamin D im Kalzium- und Knochenstoffwechsel legen Forschungsergebnisse nahe, dass Vitamin D eine Reihe weiterer wichtiger Aufgaben erfüllt. So ist der Vitamin-D-Mangel neben muskuloskelettalen Beschwerden auch mit kardiovaskulären Erkrankungen, dem metabolischen Syndrom, Diabetes mellitus Typ 2, Karzinomen sowie erhöhter Mortalität assoziiert. Weiter ist eine Vitamin-D-Defizienz mit Depressionen und einer Verschlechterung der kognitiven Funktion verbunden. Sowohl zunehmendes Alter als auch eine erhöhte Fettmasse vergrößern das Risiko für einen Vitamin-D-Mangel. Weiter gibt es Hinweise auf einen Zusammenhang zwischen Vitamin-D- und Östrogenstoffwechsel. Im Rahmen der Menopause kommt es durch den Östrogenmangel zu einem beschleunigten Knochenstoffwechsel, einer Abnahme der Knochendichte und konsekutiv zu einem erhöhten Risiko für Frakturen. Muskuloskelettale Beschwerden können die Lebensqualität beeinträchtigen, Stimmungsschwankungen treten gehäuft auf, das Risiko für metabolische und kardiovaskuläre Erkrankungen nimmt zu. Die Körperzusammensetzung verändert sich: Während die Muskelmasse abnimmt, kommt es zu einer Zunahme des Körperfettanteils, wodurch das Risiko für einen Vitamin-D-Mangel steigt. Umgekehrt kann der Vitamin-D-Mangel sowohl die Beschwerden als auch die im Rahmen der Menopause gehäuft auftretenden Erkrankungen verstärken. Hinsichtlich des Knochenstoffwechsels gibt es klare Empfehlungen, dass eine ausreichende Vitamin-D-Zufuhr erforderlich ist, um den peri- und postmenopausalen Verlust von Knochenmasse zu minimieren. Die Tatsache, dass der Vitamin-D-Mangel und die Menopause darüber hinaus auch hinsichtlich kardiovaskulärer, metabolischer, kognitiver sowie psychischer Veränderungen ein gemeinsames Risikoprofil zeigen, legt nahe, dass ein ausgeglichener Vitamin-D-Status auch hinsichtlich der kognitiven, seelischen, metabolischen und kardiovaskulären Gesundheit von peri- und

    Deflection missions to near-Earth asteroids will encounter non-negligible uncertainties in the physical and orbital parameters of the target object. In order to reliably assess future impact threat mitigation operations such uncertainties have to be quantified and incorporated into the mission design. The implementation of deflection demonstration missions offers the great opportunity to test our current understanding of deflection relevant uncertainties and their consequences, e.g., regarding kinetic impacts on asteroid surfaces. In this contribution, we discuss the role of uncertainties in the NEOTwIST asteroid deflection demonstration concept, a low-cost kinetic impactor design elaborated in the framework of the NEOShield project. The aim of NEOTwIST is to change the spin state of a known and well characterized near-Earth object, in this case the asteroid (25143) Itokawa. Fast events such as the production of the impact crater and ejecta are studied via cube-sat chasers and a flyby vehicle. Long term chang...

    According to current scientific investigations radiofrequency ablation (RFA) as a local ablative tumor therapy for unresectable liver malignancies is currently accepted as the best therapeutic choice. The results of randomized trials justify RFA for small hepatocellular carcinomas (HCC) and RFA is considered to be a viable alternative to resection for inoperable patients with limited hepatic metastatic disease, especially from colorectal cancer (CRC LM). However, surgical resection still remains the gold standard for resectable CRC LM. The intraprocedural image guidance modality of choice is computed tomography (CT) alongside CT fluoroscopy. Contrast-enhanced ultrasound (CEUS) and magnetic resonance imaging (MRI) are used for preprocedural lesion detection and differentiation as well as for follow-up and can be used to perform RFA procedures as well. This article highlights new developments in RFA. (orig.)

    Decision makers need tools to understand the priorities and to set up benchmarks and track progress in their disaster risk reduction activities, so that they can justify their decisions and investments. In this regard, Megacity Indicator System for Disaster Risk Management (MegaIST), is developed in order to be used in disaster risk management studies, for decision makers and managers to establish right strategies and proper risk reduction actions, enhance resource management and investment decisions, set priorities, monitor progress in DRM and validate decisions taken with the aim of helping disaster oriented urban redevelopment, inform investors about risk profile of the city and providing a basis for dissemination and sharing of risk components with related stakeholders; by Directorate of Earthquake and Ground Research of Istanbul Metropolitan Municipality (IMM). MegaIST achieves these goals by analyzing the earthquake risk in three separate but complementary sub-categories consisting of "urban seismic risk, coping capacity and disaster risk management index" in an integrated way. MegaIST model fosters its analyses by presenting the outputs in a simple and user friendly format benefiting from GIS technology that ensures the adoptability of the model's use. Urban seismic risk analysis includes two components, namely; Physical Risk and Social Vulnerability Analysis. Physical risk analysis is based on the possible physical losses (such as building damage, casualties etc.) due to an earthquake while social vulnerability is considered as a factor that increases the results of the physical losses in correlation with the level of education, health, economic status and disaster awareness/preparedness of society. Coping capacity analysis is carried out with the aim of understanding the readiness of the Municipality to respond and recover from a disaster in Istanbul can be defined both in terms of the Municipality's operational capacities - the capacity of the

  18. A conserved, lipid-mediated sorting mechanism of yeast Ist2 and mammalian STIM proteins to the peripheral ER.

    Sorting of yeast Ist2 to the plasma membrane (PM) or the cortical endoplasmic reticulum (ER) requires a cortical sorting signal (CSS(Ist2)) that interacts with lipids including phosphatidylinositol-4,5-bisphosphate (PI(4,5)P(2)) at the PM. Here, we show that the expression of Ist2 in mammalian cells resulted in a peripheral patch-like localization without any detection of Ist2 at the cell surface. Attached to C-termini of mammalian integral membrane proteins, the CSS(Ist2) targeted these proteins to PM-associated domains of the ER and abolished trafficking via the classical secretory pathway. The interaction of integral membrane proteins with PI(4,5)P(2) at the PM created ER-PM contacts. This process is similar to the regulated coupling of ER domains to the PM via stromal interaction molecule (STIM) proteins during store-operated Ca(2+) entry (SOCE). The CSS(Ist2) and the C-terminus of the ER-located Ca(2+) sensor STIM2 were sufficient to bind PI(4,5)P(2) and PI(3,4,5)P(3) at the PM, showing that an evolutionarily conserved mechanism is involved in the sorting of integral membrane proteins to PM-associated domains of the ER. Yeast Ist2 and STIM2 share a common basic and amphipathic signal at their extreme C-termini. STIM1 showed binding preference for liposomes containing PI(4,5)P(2), suggesting a specific contribution of lipids to the recruitment of ER domains to the PM during SOCE.

  19. Premature birth and diseases in premature infants: common genetic background?

    Science.gov (United States)

    Hallman, Mikko

    2012-04-01

    It has been proposed that during human evolution, development of obligate bipedalism, narrow birth canal cross-sectional area and the large brain have forced an adjustment in duration of pregnancy (scaling of gestational age; Plunkett 2011). Children compared to other mammals are born with proportionally small brains (compared to adult brains), suggesting shortening of pregnancy duration during recent evolution. Prevalence of both obstructed delivery and premature birth is still exceptionally high. In near term infants, functional maturity and viability is high, and gene variants predisposing to respiratory distress syndrome (RDS) are rare. Advanced antenatal and neonatal treatment practices during the new era of medicine allowed survival of also very preterm infants (gestation premature birth. Specific genes associating with diseases in preterm infants may also contribute to the susceptibility to preterm birth. Understanding and applying the knowledge of genetic interactions in normal and abnormal perinatal-neonatal development requires large, well-structured population cohorts, studies involving the whole genome and international interdisciplinary collaboration.

    2008-03-26

    Premature ejaculation (PE) is a frequent male sexual complaint that affects 20 to 30% of men. The exact aetiology is unknown: psychological/behavioristic and biogenic etiologies have been proposed. The introduction of selective serotonin reuptake inhibitors (SSRI) was revolutionary in the medical treatment of PE. However precautions should be taken because of potential adverse side effects. There is no clear consensus as to whether SSRI may represent an eventual cure of PE or will be required for life. The sexocorporal approach is an other treatment of PE, but convincing scientific treatment data are also lacking.

    2002-04-01

    Full Text Available Seven premature hydrocephalics presenting with lambdoid positional moulding (LPM were reviewed. All were treated for hydrocephalus secondary to aqueductal stenosis, Dandy Walker Syndrome and infection. Parenchymal hemorrhage, intraventricular bleed, cortical atrophy, septal agenesis, cortical anomalies and subdural hygroma were the other common associations. These children did not show expected improvement in their higher mental functions at 6 months to 5.4 years of follow-up, following the management of hydrocephalus. It was not the LPM but associated intracranial anomalies, which were most probably responsible for their poor outcome. The differentiation from posterior plagiocephaly is also highlighted.

    Full Text Available Metabolic bone disease (MBD of prematurity remains a significant problem for preterm, chronically ill neonates. The definition and recommendations for screening and treatment of MBD vary in the literature. A recent American Academy of Pediatrics Consensus Statement may help close the gap in institutional variation, but evidence based practice guidelines remain obscure due to lack of normative data and clinical trials for preterm infants. This review highlights mineral homeostasis physiology, current recommendations in screening and monitoring, prevention and treatment strategies, and an added perspective of a bone health team serving a high volume referral neonatal intensive care center.

    Premature ejaculation (PE) subjectively affects 20-30% of men globally. Until recently, understanding of PE was hampered by the absence of a widely accepted definition, paucity of evidence-based clinical studies, and the absence of an appropriate animal model. Here, we elaborate on the current definition of PE, its pathogenesis, currently available therapies, and future treatment prospects. Most treatments for PE are 'off-label' and include selective serotonin reuptake inhibitors (SSRIs), topical anesthetics, tramadol, and phosphodiesterase type 5 (PDE5) inhibitors. Such knowledge of the benefit and limitations of each treatment will help to direct future drug design and formulations.

  4. It`s not always quantity that counts. The apparent density of insulating material made of mineral wool may be a misleading quality criterion; Masse muss nicht Klasse sein. Warum die Rohdichte von Mineralwolle-Daemmstoffen ein irrefuehrendes Qualitaetsmerkmal ist

    The apparent density of insulating material made of mineral wool is a popular quality criterion that can be assessed easily but does not allow one to evaluate materials reliably. It is not the only characteristic property of such materials and it should always be used in combination with other parameters. Requirements should be based on the relevant material data, i.e. on the thermal conductivity, behavior in fire, dynamic stiffness, sound absorption properties, and mechanical strength of insulating material made of mineral wool. (orig./HW) [Deutsch] Die Rohdichte von Mineralwolle-Daemmstoffen ist zwar eine leicht feststellbare Groesse und erfreut sich grosser Beliebtheit bei der vermeintlich sicheren Beurteilung der Qualitaet. Sie ist jedoch allein niemals und nur im Verbund mit anderen Materialparametern eine kennzeichnende Eigenschaft von Mineralwolle-Daemmstoffen. Bei der Formulierung von Anforderungen sollte man sich demnach auf die relevanten Materialdaten von MW-Daemmstoffen beschraenken: Waermeleitfaehigkeit, Brandverhalten, dynamische Steifigkeit, Schallabsorptionsvermoegen, mechanische Festigkeit.

    Isotretinoin has been considered a unique drug for acne treatment. However, it is associated with numerous adverse effects. Isotretinoin can trigger premature ventricular contractions. This report describes a 33-year-old-woman who presented with palpitations for 1 week while undergoing 1-month isotretinoin treatment for mild-moderate facial acne. An electrocardiogram and Holter monitoring showed premature ventricular contractions during isotretinoin (Roaccutane, Roche) treatment. Isotretinoin-related premature ventricular contractions were strongly suggested in this case due to the existence of documented premature ventricular contractions on electrocardiograms and the disappearance of these premature ventricular contractions two weeks after termination of the treatment To the authors' knowledge, there has been 1 reported case of premature ventricular contractions linked to isotretinoin use; this report describes a second such case.

    Hughes, J R; Fino, J J; Hart, L A

    1987-07-01

    A distinctive pattern called premature temporal theta (PT theta) was studied in 436 infants, ranging in age from 24 to 46 weeks. The pattern is seen in early prematurity, maximizes at 29-31 weeks and then diminishes and disappears near term. Usually the pattern is found independently on both temporal areas, but with a right-sided preference. Patients without PT theta or with a significantly low amount had either neurological or non-neurological (medical) conditions. With age there is a tendency for an increase in frequency and a decrease in amplitude. Five different peaks in the amount of this pattern are seen at approximately every month. Unilateral PT theta tends to be seen in older babies, more often on the right side and with an abnormal EEG. An abnormal EEG is usually associated with a delay in both the appearance and disappearance of this wave form. PT theta is also associated mainly with REM or active sleep. A polynomial rather than an exponential or power function best describes these data with changes of age. PT theta may arise from the inferior temporal gyrus and/or especially the transverse gyrus.

  8. Premature birth: An Enigma for the Society?

    Full Text Available Infants born preterm are at greater risk than infants born at term for mortality and a variety of health and developmental problems. Complications include acute respiratory, gastrointestinal, immunologic, central nervous system, hearing, and vision problems, as well as longer-term motor, cognitive, visual, hearing, behavioral, social-emotional, health, and growth problems. The birth of a preterm infant can also bring considerable emotional and economic costs to families and have implications for public-sector services, such as health insurance, educational, and other social support systems. The greatest risk of mortality and morbidity is for those infants born at the earliest gestational ages. However, those infants born nearer to term represent the greatest number of infants born preterm and also experience more complications than infants born at term. Preterm birth is a complex cluster of problems with a set of overlapping factors of influence. Its causes may include individual-level behavioral and psychosocial factors, neighborhood characteristics, environmental exposures, medical conditions, infertility treatments, biological factors and genetics. Many of these factors occur in combination, particularly in those who are socioeconomically disadvantaged or who are members of racial and ethnic minority groups. The empirical investigation was carried out to draw correlation between preterm birth and eventuality. This paper deals with various issues related to the premature deliveries from socio-biological perspectives.

    The validation of the Plant Dynamics Code (PDC) developed at Argonne National Laboratory (ANL) for the steady-state and transient analysis of supercritical carbon dioxide (sCO2) systems has been continued with new test data from the Naval Nuclear Laboratory (operated by Bechtel Marine Propulsion Corporation) Integrated System Test (IST). Although data from three runs were provided to ANL, only two of the data sets were analyzed and described in this report. The common feature of these tests is the power-neutral operation of the turbine-compressor shaft, where no external power through the alternator was provided during the tests. Instead, the shaft speed was allowed to change dictated by the power balance between the turbine, the compressor, and the power losses in the shaft. The new test data turned out to be important for code validation for several reasons. First, the power-neutral operation of the shaft allows validation of the shaft dynamics equations in asynchronous mode, when the shaft is disconnected from the grid. Second, the shaft speed control with the compressor recirculation (CR) valve not only allows for testing the code control logic itself, but it also serves as a good test for validation of both the compressor surge control and the turbine bypass control actions, since the effect of the CR action on the loop conditions is similar for both of these controls. Third, the varying compressor-inlet temperature change test allows validation of the transient response of the precooler, a shell-and-tube heat exchanger. The first transient simulation of the compressor-inlet temperature variation Test 64661 showed a much slower calculated response of the precooler in the calculations than the test data. Further investigation revealed an error in calculating the heat exchanger tube mass for the PDC dynamic equations that resulted in a slower change in the tube wall temperature than measured. The transient calculations for both tests were done in two steps. The

    2011-04-01

    Full Text Available The article explores mechanisms of non-developing the Ist trimester pregnancy on the basis of studying frequency of polymorphic alleles in folate metabolism genes MTHFR C677T, MTHFR A1298C, MTRR A66G, MTR A2756G, homocysteine level, platelet and plasma haemostasis sections.Polymorphism in MTHFR, MTRR, and MTR genes of folate metabolism causes hyperhomocysteinemia and thrombophilic changes. In conditions of genetically accustomed thrombophilic changes the desynchronization of fibrinolysis and fibrin formation processes during implantation occurs that leads to poor trophoblast invasion and its inadequacy, which in turn causes miscarriage due to non-developing pregnancy in the Ist trimester.

  15. [Premature rupture of membranes and chorioamnionitis].

    Science.gov (United States)

    Lopez Garcia, R

    1988-01-01

    Despite advances in perinatal medicine in the past decade, the diagnosis and treatment of premature rupture of membranes remain controversial. Premature rupture occurs in 2.7-7.0% of pregnancies and most cases occur spontaneously without apparent cause. The disparity in reported rates of premature rupture is due to differences in the definition and diagnostic criteria for premature rupture and lack of comparability in the populations studied. Mexico's National Institute of Perinatology has adopted the definition of the American COllege of Gynecology and Obstetrics which views premature rupture as that occurring before regular uterine contractions that produce cervical dilation. 8.8% of its patients have premature rupture according to this definition. 20% of cases occur before the 36th week of pregnancy. Treatment of rupture occurring before 37 weeks must balance the threat of amniotic infection with the dangers of premature birth. Infections appear more common in low income patient populations. Chorioamnionitis is a serious complication of pregnancy and is the main argument against conservative treatment of premature rupture. The rate of maternal infection is directly related to the time elapsing between rupture of the membranes and birth. The rate increases after the 1st 24 hours and is at least 10 times higher after 72 hours. But recent studies suggest that there is no considerable increase in infection if vaginal explorations are avoided and careful techniques are used in treating the patient. Those who advise conservative treatment believe that prenatal outcomes are better because respiratory disease syndrome due to prematurity is avoided. Conservative management requires a white cell count at least every 24 hours and measurement of pulse, maternal temperature, and fetal heart rate ideally every 4 hours. Perinatal mortality rates due to premature rupture of membranes range from 2.5-50%. The principal causes are respiratory disease syndrome, infection, asphyxia

  16. Human milk for the premature infant

    Underwood, Mark A.

    2012-01-01

    Synopsis Premature infants are a heterogeneous group with widely differing needs for nutrition and immune protection with risk of growth failure, developmental delays, necrotizing enterocolitis, and late-onset sepsis increasing with decreasing gestational age and birth weight. Human milk from women delivering prematurely has more protein and higher levels of many bioactive molecules compared to milk from women delivering at term. Human milk must be fortified for small premature infants to achieve adequate growth. Mother’s own milk improves growth and neurodevelopment and decreases the risk of necrotizing enterocolitis and late-onset sepsis and should therefore be the primary enteral diet of premature infants. Donor milk is a valuable resource for premature infants whose mothers are unable to provide an adequate supply of milk, but presents significant challenges including the need for pasteurization, nutritional and biochemical deficiencies and a limited supply.

    Premature infants often cannot successfully and coordinately complete their oral feeding. Mature sucking, swallowing, and respiration activities are crucial indicators for the survival of newborn infants. Due to the vulnerability and unobvious muscle activities of premature infants, current clinical care givers mainly depend on the subjective behavioral observation of infants during oral feeding. There is still lack of an integrated oral feeding monitoring system to objectively and quantifiably monitor the related physiological parameters of premature infants. In this study, a wireless multi-parameter monitoring system for oral feeding of premature infants was proposed to monitor the sucking-swallowing-respiratory activities and the heart rate variability to provide quantitative indices of oral feeding. Here, a novel sucking pressure sensing module was also developed to monitor the premature infant's sucking pressure under oral feeding to avoid the immersion influence of milk. The experimental results showed that the proposed system detected the related physiological parameters of premature infants during oral feeding effectively and may provide an objective clinical evaluation tool for oral feeding ability and safety of premature infants in the future.

    Presentation, prognosis, and management of premature ventricular complexes (PVCs) vary significantly among patients and depend on PVC characteristics as well as patient comorbidities. Presentation can range from incidental discovery in an asymptomatic patient to debilitating heart failure. Prognosis depends on, among other factors, the presence or absence of structural heart disease, PVC burden and other factors detailed in this review. Our understanding of the clinical significance of frequent PVCs, particularly as it relates to development of cardiomyopathy, has advanced greatly in the past decade. In this article, we explore the mechanisms governing PVC initiation and discuss prevalence and frequency of PVCs in the general population. We also explore prognostic implications based on PVC frequency as well as the presence or absence of underlying heart disease. We then take a focused look at PVC-induced cardiomyopathy and identify predictors for developing cardiomyopathy. Finally, we discuss clinical evaluation and management of patients presenting with frequent PVCs. Management can include clinical observation, addressing reversible causes, lifestyle modification, pharmacotherapy, or catheter ablation.

    Magnetic resonance imaging (MRI) of the lungs is becoming increasingly appreciated as a third diagnostic imaging modality besides chest x-ray and computed tomography (CT). Its value is well acknowledged for pediatric patients or for scientific use particularly when radiation exposure should be strictly avoided. However, the diagnosis of interstitial lung disease is the biggest challenge of all indications. The objective of this article is a summary of the current state of the art for diagnostic MRI of interstitial lung diseases. This article reflects the results of a current search of the literature and discusses them against the background of the authors own experience with lung MRI. Due to its lower spatial resolution and a higher susceptibility to artefacts MRI does not achieve the sensitivity of CT for the detection of small details for pattern recognition (e.g. fine reticulation and micronodules) but larger details (e.g. coarse fibrosis and honeycombing) can be clearly visualized. Moreover, it could be shown that MRI has the capability to add clinically valuable information on regional lung function (e.g. ventilation, perfusion and mechanical properties) and inflammation with native signal and contrast dynamics. In its present state MRI can be used for comprehensive cardiopulmonary imaging in patients with sarcoidosis or for follow-up of lung fibrosis after initial correlation with CT. Far more indications are expected when the capabilities of MRI for the assessment of regional lung function and activity of inflammation can be transferred into robust protocols for clinical use.

    Zygosaccharomyces bailii is one of the most problematic spoilage yeast species found in the food and beverage industry particularly in acidic products, due to its exceptional resistance to weak acid stress. This article describes the annotation of the genome sequence of Z. bailii IST302, a strain recently proven to be amenable to genetic manipulations and physiological studies. The work was based on the annotated genomes of strain ISA1307, an interspecies hybrid between Z. bailii and a closely related species, and the Z. bailii reference strain CLIB 213T. The resulting genome sequence of Z. bailii IST302 is distributed through 105 scaffolds, comprising a total of 5142 genes and a size of 10.8 Mb. Contrasting with CLIB 213T, strain IST302 does not form cell aggregates, allowing its manipulation in the laboratory for genetic and physiological studies. Comparative cell cycle analysis with the haploid and diploid Saccharomyces cerevisiae strains BY4741 and BY4743, respectively, suggests that Z. bailii IST302 is haploid. This is an additional trait that makes this strain attractive for the functional analysis of non-essential genes envisaging the elucidation of mechanisms underlying its high tolerance to weak acid food preservatives, or the investigation and exploitation of the potential of this resilient yeast species as cell factory. © FEMS 2017.

  6. Role of SKD1 Regulators LIP5 and IST1-LIKE1 in Endosomal Sorting and Plant Development1[OPEN

    Science.gov (United States)

    Paez-Valencia, Julio; Miller, Nathan D.; Goodman, Kaija

    2016-01-01

    SKD1 is a core component of the mechanism that degrades plasma membrane proteins via the Endosomal Sorting Complex Required for Transport (ESCRT) pathway. Its ATPase activity and endosomal recruitment are regulated by the ESCRT components LIP5 and IST1. How LIP5 and IST1 affect ESCRT-mediated endosomal trafficking and development in plants is not known. Here we use Arabidopsis mutants to demonstrate that LIP5 controls the constitutive degradation of plasma membrane proteins and the formation of endosomal intraluminal vesicles. Although lip5 mutants were able to polarize the auxin efflux facilitators PIN2 and PIN3, both proteins were mis-sorted to the tonoplast in lip5 root cells. In addition, lip5 root cells over-accumulated PIN2 at the plasma membrane. Consistently with the trafficking defects of PIN proteins, the lip5 roots showed abnormal gravitropism with an enhanced response within the first 4 h after gravistimulation. LIP5 physically interacts with IST1-LIKE1 (ISTL1), a protein predicted to be the Arabidopsis homolog of yeast IST1. However, we found that Arabidopsis contains 12 genes coding for predicted IST1-domain containing proteins (ISTL1–12). Within the ISTL1–6 group, ISTL1 showed the strongest interaction with LIP5, SKD1, and the ESCRT-III-related proteins CHMP1A in yeast two hybrid assays. Through the analysis of single and double mutants, we found that the synthetic interaction of LIP5 with ISTL1, but not with ISTL2, 3, or 6, is essential for normal plant growth, repression of spontaneous cell death, and post-embryonic lethality.

    The relation of sexual behaviour during pregnancy to the initiation of labour was investigated in 358 patients of whom 58 were delivered after premature labour and 300 were delivered spontaneously at term. In all patients the mean weekly coital frequency and the frequency of orgasm were investigated by means of a retrospective questionnaire. There was no significant difference in coital or orgasmic frequency between the women who had a premature labour and those who had a spontaneous delivery at term. This was also true when those having premature labour were divided into those starting labour with ruptured membranes and those starting with contractions.

    A case is presented of a premature newborn of 27 weeks gestation and weighing 420 grams who was delivered as a result of a maternal pre-eclampsia and retarded intra-uterine growth. During the 125 days of hospitalisation, an individual care plan based on the Virginia Henderson model was devised and applied to both the child and her parents using NANDA diagnostics, interventions according to the NIC classification, and the expected results according to the NOC classification. The Marjory Gordon functional patterns were used for the initial assessment. By applying the pre-term newborn (PTNB) plan, all their needs were provided and were modified throughout the hospital stay, with new needs that were added to the established ones. These required a continuous assessment with the subsequent adapting of the care plan. Likewise, the care required by the parents varied from the initial grief due to the possible loss of their child to learning the alarm signs and the home care that their child would need. The child was finally discharged weighing 2900 grams and with normal neurological and psychomotor development, although with a lower weight appropriate to her age. Currently, at 2 years old, the child has a normal neurological and psychomotor development, but with weight and size lower than the P(3) percentile. She requires speech therapy treatment due to paralysis of the right vocal cord.

    2016-08-01

    Premature ejaculation (PE) is a male sexual dysfunction that creates considerable anguish for the man, his partner and their relationship. PE is not one disorder but includes the four subtypes (lifelong, acquired, natural and subjective) each with unique psychological concerns and issues. Psychological treatment for men and couples with PE addresses sexual skills/techniques but also focuses on issues of self-esteem, performance anxiety and interpersonal conflict. The outcome studies for psychotherapy alone are difficult to interpret and compare because of poor methodological design (lack of control groups, small sample size, poor outcome measures and lack of follow-up). However, the few studies that surmount these methodological hurdles suggest that psychological intervention offers men and couples a promising treatment option. Combination pharmaco- and psychotherapy is the most promising intervention for lifelong and acquired PE and offers superior efficacy to drug alone. This is because men and couples learn sexual skills, address the intrapsychic, interpersonal and cognitive issues that precipitate and maintain the dysfunction.

  11. The epidemiology of premature ejaculation.

    Vast advances have occurred over the past decade with regards to understanding the epidemiology, pathophysiology and management of premature ejaculation (PE); however, we still have much to learn about this common sexual problem. As a standardized evidence-based definition of PE has only recently been established, the reported prevalence rates of PE prior to this definition have been difficult to interpret. As a result, a large range of conflicting prevalence rates have been reported. In addition to the lack of a standardized definition and operational criteria, the method of recruitment for study participation and method of data collection have obviously contributed to the broad range of reported prevalence rates. The new criteria and classification of PE will allow for continued research into the diverse phenomenology, etiology and pathogenesis of the disease to be conducted. While the absolute pathophysiology and true prevalence of PE remains unclear, developing a better understanding of the true prevalence of the disease will allow for the completion of more accurate analysis and treatment of the disease.

  12. [Sexological intervention on premature ejaculation].

    Strategies, recommendations and techniques proposed by sex therapy for intervention on premature ejaculation, have represented for nearly four decades the most effective model of intervention in this sexual dysfunction, which currently is complemented by the efficacy of dapoxetine drug treatment. Clinical experience and recent studies support that combined intervention offers the best therapeutic results. In addition in sex therapy, etiologic diagnosis is obtained from the analysis of the interrelationship of the couple. Diagnostic and therapeutic intervention has to be always centered in the relationship, so the techniques and resources must be applied with the expectation of being implemented in the sexual interaction. It will therefore be the relationship that receive treatment, even if medication is used for one of the members of the couple. On the other hand, this model of intervention can be implemented by a professional with training, although not necessarily a specialist.

  13. Medical therapy for premature ejaculation

    Premature ejaculation (PE) is a common male sexual dysfunction. Advances in PE research have been hampered owing to a nonstandardized definition of PE, until the definition by the International Society of Sexual Medicine (ISSM) in 2009. Once the diagnosis of PE is established through a thorough history, a variety of medical therapies is available, including tricyclic antidepressants, selective serotonin reuptake inhibitors (SSRIs), centrally acting opiates, phosphodiesterase 5 inhibitors and topical desensitizing creams. Most of these treatments increase the intravaginal ejaculation latency time (IELT) and patient satisfaction scores, with the most convincing evidence for SSRIs and topical creams. Daily SSRIs such as paroxetine, although efficacious, do have a substantial and prolonged side effect profile. Dapoxetine, which is a on-demand SSRI, is the only licensed drug for the treatment of PE, increasing IELT by a factor of 2.5 to 3 with limited and tolerable side effects. In the near future, the topical aerosol PSD502 is due to be licensed for the treatment of PE, increasing IELT by up to a factor of 6 but having minimal local and negligible systemic side effects.

    Full Text Available Das Konzept des "bipolaren Spektrums" nach Akiskal & Pinto (1999 beinhaltet die Vorstellung, dass viele, nach den aktuellen Diagnosekriterien bisher als unipolare Depressionen klassifizierte Krankheitsbilder in Wirklichkeit bipolare Erkrankungen darstellen, und die klassischen Stimmungsstabilisatoren Lithium, Valproat und Carbamazepin Mittel der Wahl in der Behandlung dieser depressiven Episoden mit den "weichen" bipolaren Merkmalen darstellen. Während verschiedene Untersuchungen während der vergangenen Jahre Teile des theoretischen Konzepts der Bipolarität von Akiskal validiert haben, bleibt abzuwarten, inwieweit der vornehmliche Einsatz der klassischen Stimmungsstabilisatoren bei diesen Krankheitsbildern gerechtfertigt ist, da bisher hierzu keine kontrollierten randomisierten Studien durchgeführt bzw. veröffentlicht worden sind. Bis dahin könnte die Kombination von Antidepressiva, insbesondere selektiven Serotonin- Wiederaufnahmehemmern (SSRI, mit dem klassischen Stimmungsstabilisator Lithium, aber auch mit den atypischen Antipsychotika Olanzapin bzw. Quetiapin im Sinne einer Augmentation einen sinnvollen Therapiebaustein in der Behandlung depressiver Episoden mit weichen bipolaren Merkmalen darstellen, da sich diese Substanzen/Therapieverfahren sowohl in der Akutbehandlung depressiver Episoden auf dem Boden majorer Depressionen als auch bipolarer Erkrankungen als wirksam erwiesen haben.

    Full Text Available Kurzfassung: Bis heute wurden hunderte möglicher "neuer" Risikofaktoren mit dem Auftreten kardiovaskulärer Erkrankungen assoziiert. Nur wenige sind ausreichend untersucht, um ihren Stellenwert für die Risikoprädiktion, verglichen mit der Risikoeinschätzung auf Grundlage konventioneller Risikofaktoren, bestimmen zu können. In der vorliegenden Arbeit werden neue kardiovaskuläre Risikofaktoren beschrieben und ihr Beitrag zur Risikoprädiktion beleuchtet. Sie scheinen vor allem in Subgruppen und im intermediären Risikobereich dazu beizutragen, therapeutische Interventionen ökonomischer zu steuern. Das gleiche gilt für die Einbeziehung von Gefäßwandschäden als "integrative Biomarker". Die bisher publizierten genetisch-epidemiologischen Studien unterstreichen die Richtigkeit des Konzeptes eines genomweiten Forschungsansatzes zur Identifikation neuer Risikofaktoren der Arteriosklerose. Entscheidend bei diesem Ansatz ist der hypothesenfreie Zugang, der zur Identifizierung bisher unbeachteter Gene führt. Die Ergebnisse werden bislang noch unbekannte Krankheitsmechanismen aufdecken, zum weiteren Verständnis der Ätiopathogenese der Arteriosklerose beitragen, neue "drug targets" identifizieren und so unser zukünftiges Handeln auf der Versorgungsebene mitbestimmen.

    Energy-optimised operation can do much to improve the profitability of hotels and restaurants. According to the statisitics of DEHOGA, the German Association of Hotel and Restaurant Enterprises, the cost of operating heating, ventilation, and air conditioning plants and other electricity consumers amount to approx. 4% of the total cost of a gastronomic business. Reducing this contribution to 2% will raise profits by about the same factor. ``Frankfurter Hof``, a luxury hotel of the Steigenberger chain located in the metropolis on the Main, demonstrates that this sort of calculation is more than just theory. (orig.) [Deutsch] Fuer Hotels und Gaststaetten ist die energieoptimierte Betriebsfuehrung von gewinntraechtiger Bedeutung.

Im Unterschied zur klassischen Lebensphilosophie und zu den an sie anknüpfenden ethischen Entwürfen wird das Leben bei Schopenhauer aber nicht als Zweck betrachtet, sondern als Mittel zu einem anderen Zweck, nämlich für die Ethik, die in der Verneinung des Willens zum Leben gipfelt. Schon in den frühesten handschriftlichen Aufzeichnungen verwendet Schopenhauer verschiedene Metaphern, um das Leben als Medium der ethischen Erkenntnis zu charakterisieren. Besonders häufig tritt dabei das Bild vom Leben als Spiegel auf, in dem der Mensch sein eigenes Wesen und damit auch das Wesen der Welt erblickt. Im Hauptwerk wird dann dieses Bild vom Begriff der Objektivation des Willens abgelöst. Insofern die höchste und deutlichste Objektivation des Willens der Lebenslauf des menschlichen Individuums darstellt, ist Schopenhauers Lebensbegriff eng mit seiner Charakterlehre verknüpft. In dem Beitrag wird das verwickelte Verhältnis von Leben, Erkennen und Ethik vor dem Hintergrund der proto-hermeneutischen Metaphysikkonzeption Schopenhauers anhand der Entwicklung der Spiegelmetapher betrachtet.

Methods: evaluative, quantitative study with investigative nature conducted with 19 mothers of hospitalized premature newborns. Data were obtained from closed questions, answered by mothers. Results: from the participants, two (10.5% reported that newborns are unable to feel pain. From the 17 mothers who said that premature babies can feel pain, the majority (94.1% identified crying as a characteristic of pain sensation. Eleven (64.7% stated that uneasiness is a sign of pain in newborns. Conclusion: for the proper management of neonatal pain it is essential that mothers know the signs of pain in premature newborns, and that health professionals instruct this recognition, through the enhancement of the maternal presence and practice of effective communication between professionals and newborns’ families.

  4. Future Applications of Antioxidants in Premature Infants

    2012-01-01

    Purpose of Review This review will examine the unique susceptibility of premature infants to oxidative stress, the role of reactive oxygen species (ROS) in the pathogenesis of common disorders of the preterm infant, and potential for therapeutic interventions using enzymatic and/or non-enzymatic antioxidants. Recent Findings Oxidative stress is caused by an imbalance between the production of ROS and the ability to detoxify them with the help of antioxidants. The premature infant is especially susceptible to ROS-induced damage because of inadequate antioxidant stores at birth, as well as impaired upregulation in response to oxidant stress. Thus, the premature infant is at increased risk for the development of ROS-induced diseases of the newborn, such as bronchopulmonary dysplasia, retinopathy of prematurity, necrotizing enterocolitis, and periventricular leukomalacia. Summary Potential therapies for ROS-induced disease include both enzymatic and non-enzymatic antioxidant preparations. More research is required to determine the beneficial effects of supplemental antioxidant therapy. PMID:21150443

    Hepatocellular carcinoma (HCC) is the fifth most common cancer worldwide and represents the main cause of death among European patients with liver cirrhosis. Only 30-40% of patients diagnosed with HCC are candidates for curative treatment options (e.g. surgical resection, liver transplantation or ablation). The remaining majority of patients must undergo local regional and palliative therapies. Transvascular ablation of HCC takes advantage of the fact that the hypervascularized HCC receives most of its blood supply from the hepatic artery. In this context transvascular ablation describes different therapy regimens which can be assigned to four groups: cTACE (conventional transarterial chemoembolization), bland embolization (transarterial embolization TAE), DEB-TACE (TACE with drug-eluting beads, DEB) and SIRT (selective internal radiation therapy, radioembolization). Conventional TACE is the most common type of transvascular ablation and represents a combination of intra-arterial chemotherapy and embolization with occlusion of the arterial blood supply. However, there is no standardized regimen with respect to the chemotherapeutic drug, the embolic agent, the usage of lipiodol and the interval between the TACE procedures. Even the exact course of a cTACE procedure (order of chemotherapy or embolization) is not standardized. It remains unclear whether or not intra-arterial chemotherapy is definitely required as bland embolization using very small, tightly calibrated spherical particles (without intra-arterial administration of a chemotherapeutic drug) shows tumor necrosis comparable to cTACE. For DEB-TACE microparticles loaded with a chemotherapeutic drug combine the advantages of cTACE and bland embolization. Thereby, a continuing chemotherapeutic effect within the tumor might cause a further increase in intratumoral cytotoxicity and at the same time a decrease in systemic toxicity. (orig.)

  16. Utilization of the Premature Birth Knowledge Scale to Assess Pediatric Provider Knowledge of Neurodevelopmental Outcomes.

    Science.gov (United States)

    Kelly, Michelle M; Dean, Spencer

    Prematurity affects a significant portion (10-12%) of children in the Unites States, with potential for physical, psychological, neurodevelopmental, and behavioral impairments continuing long past the neonatal period. The specific aim of this research was to evaluate pediatric primary and specialty care providers' knowledge and understanding of neurodevelopmental outcomes of children born prematurely. Pediatric nurse practitioner (PNP) members of the National Association of Pediatric Nurse Practitioners participated in an online survey using the 33-item Premature Birth Knowledge Scale (PB-KS) to assess their knowledge of current neurodevelopmental outcomes of children born prematurely. Neither years of practice as a registered nurse nor as a PNP predicted performance on the PB-KS. The mean score on the PB-KS in the PNP sample was 17.8 (possible score = 0-33), with a mean accuracy of 53.9%. Higher scores on the PB-KS were correlated with higher perceived level of preparation to care for children born prematurely. To our knowledge, this is the first study to use the PB-KS with pediatric primary and specialty providers. PNPs are uniquely situated to educate and support families facing the long-term consequences of premature birth; to do so they must maintain accurate understanding of current outcomes.

    Full Text Available istSOS (Istituto scienze della Terra Sensor Observation Service is an implementation of the Sensor Observation Service (SOS standard from the Open Geospatial Consortium. The development of istSOS started in 2009 in order to provide a simple implementation of the SOS for the management, provision and integration of hydro-meteorological data collected in Canton Ticino (Southern Switzerland. istSOS is an Open Source, entirely written in Python and based on reliable software like PostgreSQL/PostGIS and Apache/mod_wsgi. This paper illustrates the latest software enhancements, including a RESTful Web service and a Web-based graphical user interface, which enable a better and simplified interaction with measurements and SOS service settings. The robustness of the implemented solution has been validated in a real-case application: the Verbano Lake Early Warning System. In this application, near real-time data have to be exchanged by inter-regional partners and used in a hydrological model for lake level forecasting and flooding hazard assessment. This system is linked with a dedicated geoportal used by the civil protection for the management, alert and protection of the population and the assets of the Locarno area. Practical considerations, technical issues and foreseen improvements are presented and discussed.

    The increasing volume of data describing human disease processes and the growing complexity of understanding, managing, and sharing such data presents a huge challenge for clinicians and medical researchers. This paper presents the @neurIST system, which provides an infrastructure for biomedical research while aiding clinical care, by bringing together heterogeneous data and complex processing and computing services. Although @neurIST targets the investigation and treatment of cerebral aneurysms, the system's architecture is generic enough that it could be adapted to the treatment of other diseases. Innovations in @neurIST include confining the patient data pertaining to aneurysms inside a single environment that offers clinicians the tools to analyze and interpret patient data and make use of knowledge-based guidance in planning their treatment. Medical researchers gain access to a critical mass of aneurysm related data due to the system's ability to federate distributed information sources. A semantically mediated grid infrastructure ensures that both clinicians and researchers are able to seamlessly access and work on data that is distributed across multiple sites in a secure way in addition to providing computing resources on demand for performing computationally intensive simulations for treatment planning and research.

    PURPOSE: To report the incidence, severity and risk factors of retinopathy of prematurity (ROP in premature infants with late ROP examination in Farabi Eye Hospital. METHODS: In a retrospective study from January 2001 to July 2007, hospital records of premature infants who were examined later than 9 weeks after birth were reviewed to determine the incidence, severity and possible risk factors of ROP including gender, singleton or multiple gestations, gestational age (GA, birth weight (BW, oxygen therapy, blood transfusion, phototherapy, respiratory distress syndrome (RDS, mechanical ventilation, intraventricular hemorrhage and sepsis as well as age at initial examination. RESULTS: Out of a total of 797 infants referred for ROP screening during the study period, 216 (27.1% had late examinations at a mean age of 141.7±150.4 (range 64-1,460 days. Of these, 87 (40.3% had different stages of ROP, 65 (30.1% had stage 4 or 5 disease including 34 (16.2% infants with stage 5 ROP in both eyes which was untreatable. Lower GA (P < 0.001, RDS (P=0.041 and blood transfusion (P=0.009 were associated with the development of ROP. CONCLUSION: The overall prevalence of ROP and the incidence

    To determine whether serum fructosamine which is a good marker for detecting hyperglycemia during the previous 2 to 3 wk in infants could predict the development of retinopathy of prematurity in very low birth weight infants. One hundred sixty seven premature infants who had a birth weight of < 1500 g and a gestational age of less than 32 wk were investigated in the present study. Blood glucose was measured at the bedside and infants were recorded as hyperglycemic if their mean blood glucose levels were higher than 150 mg/dL. Serum corrected fructosamine level was obtained from the cord blood at birth and after the first month of life. The infants' eyes were examined by ophthalmologists to detect retinopathy of prematurity at the gestational age of 32 wk or at four wk after birth, whichever came first. Corrected fructosamine was 319.6 ± 59.6 and 272.8 ± 50.6 mmol/l for group 1 on 1(st) and 30(th) day respectively; 320 ± 61.7 and 268.2 ± 47.3 mmol/l for groups 2 + 3 on 1(st) and 30(th) day respectively which did not differ between groups (p = 0.766 and p = 0.665), whereas duration of hyperglycemia was 1.69 ± 1.1 day in group 1 compared with 3.05 ± 2.4 day in groups 2 + 3 which was significantly different (p = 0.019). The multivariate regression analysis indicated that the duration of hyperglycemia in days was significantly correlated with the development of retinopathy of prematurity (OR 3.26; 95% CI 1.09-9.80; p = 0.035). Although the duration of hyperglycemia may contribute to the development of retinopathy of prematurity, serum corrected fructosamine does not have a good predictive value in developing retinopathy of prematurity in very-low-birth-weight (VLBW) infants.

    1991-01-01

    The purpose of this study was to examine the effects of music on selected stress behaviors, weight, caloric and formula intake, and length of hospital stay. Subjects were 52 preterm and low birth weight newborns in a newborn intensive care unit (NBICU) who were in stable condition and restricted to isolettes. Subjects in the experimental and control groups were matched for equivalency based on sex, birth weight, and diagnostic criticality. Eleven males and 15 females were assigned to the control group and received routine auditory stimulation. The experimental group of 11 males and 15 females received music stimulation, which consisted of approximately 60 minutes of tape recorded vocal music, including lullabies and children's music, and routine auditory stimulation. Thirty-minute segments of the recording were played alternatively with 30 minutes of routine auditory stimulation three times daily. Exposure to music stimulation occurred only during the infants' stay in the NBICU. Results suggest music stimulation may have significantly reduced initial weight loss, increased daily average weight, increased formula and caloric intake, significantly reduced length of the NBICU and total hospital stays, and significantly reduced the daily group mean of stress behaviors for the experimental group. Data analyses suggest the length of hospital stay may be correlated with the amount of stress experienced by the neonate and not with weight gains. Theoretical and practical aspects of these results are discussed.

    This meta-analysis on music research with premature infants in neonatal intensive care units (NICU) showed an overall large, significant, consistent effect size of almost a standard deviation (d =.83) (Cohen, 1998). Effects were not mediated by infants' gestational age at the time of study, birthweight, or type of music delivery nor by physiologic, behavioral, or developmental measures of benefit. The homogeneity of findings suggests that music has statistically significant and clinically important benefits for premature infants in the NICU. The unique acoustic properties that differentiate music from all other sounds are discussed and clinical implications for research-based music therapy procedures cited.

    Full Text Available We examined the effects of prematurity (37 weeks of gestation and low birthweight (2500 g on mental health outcomes among US children aged 2–17 years. The 2011-2012 National Survey of Children’s Health ( = 95,677 was used to estimate prevalence of parent-reported mental health problems in children. Prevalence of mental disorders was 22.9% among children born prematurely, 28.7% among very-low-birth-weight (1500 g children, and 18.9% among moderately low-birth-weight (1500–2499 g children, compared with 15.5% in the general child population. Compared to those born full term, children born prematurely had 61% higher adjusted odds of serious emotional/behavioral problems, 33% higher odds of depression, and 58% higher odds of anxiety. Children born prematurely had 2.3 times higher odds of autism/ASD, 2.9 times higher odds of development delay, and 2.7 times higher odds of intellectual disability than term children. Very-low-birth-weight children had 3.2 times higher odds of autism/ASD, 1.7 times higher odds of ADD/ADHD, 5.4 times higher odds of development delay, and 4.4 times higher odds of intellectual disability than normal-birth-weight children. Social factors were significant predictors of mental disorders in both premature/low-birth-weight and term/normal-birth-weight children. Neurodevelopmental conditions accounted for the relationship between prematurity and depression/anxiety/conduct problems. Prematurity and low birthweight are significant risk factors for mental health problems among children.

    Full Text Available Background: Birth of a premature neonate is associated with hospital admission and separation from the family. Admission of the neonates intervenes on infant-mother attachment and so adversely affects on the quality of care given by the mother, and subsequently increases the risk of delayed behavioral problems in the children. Aim: To assess the effectiveness of mother empowerment program on the premature infant-mother attachment. Methods: In this randomized clinical trial, 70 mothers of premature infants, admitted to the neonatal intensive care unit (NICU of Omolbanin hospital of Mashhad in 2014, were divided into of intervention and control groups. The Empowerment program was a multi-step treatment program, in which information about the premature infants was provided to mothers through an illustrated booklet with a workbook and audio file in each step. Mothers in the control group received information and routine care according to the hospital guideline. The mother-infant attachment was measured after the intervention using the maternal and neonatal behaviors Avant tool. Data analysis was performed using chi-square and t-student tests by SPSS software version 11.5. Results:The mean scores of maternal attachment behaviors after the intervention in the empowerment and control groups were (56.62±8.06 and (39.51±7.77, respectively; the difference between the groups was statistically significant (P

    In Japan, all 47 prefectures conduct routine air quality monitoring at 1145 stations throughout the country to assess environmental effects. This study aims to provide a better understanding of possible estimations of premature mortality in Japan caused by exposure to monitored and modeled concentrations of tropospheric ozone during the period from January to December, 2005. The spatial distribution and temporal variation of ozone concentrations were modeled using the Models-3 Community Multiscale Air Quality modeling system coupled with the Regional Emission Inventory in Asia (CMAQ/REAS). Premature mortality caused by exposure to ozone was calculated assuming a relative risk (RR) value of 1.003 [95% Confidence Interval (CI): 1.001-1.004] for concentrations above 35 ppb according to the SOMO35 index (annual Sum of daily maximum 8-h Ozone Means Over 35 ppb) recommended by WHO (2008). Based on CMAQ/REAS simulations, the estimated all-cause premature mortality in 2005 is about 13,000 (95% CI: 4320-17,300) cases. This value is 2.5 times greater than the estimated premature mortality based on monitored ozone concentrations, which is 5220 (95% CI: 1740-6960) cases.

  16. Optimal oxygen saturation in premature infants

    Directory of Open Access Journals (Sweden)

    Meayoung Chang

    2011-09-01

    Full Text Available There is a delicate balance between too little and too much supplemental oxygen exposure in premature infants. Since underuse and overuse of supplemental oxygen can harm premature infants, oxygen saturation levels must be monitored and kept at less than 95% to prevent reactive oxygen species-related diseases, such as retinopathy of prematurity and bronchopulmonary dysplasia. At the same time, desaturation below 80 to 85% must be avoided to prevent adverse consequences, such as cerebral palsy. It is still unclear what range of oxygen saturation is appropriate for premature infants; however, until the results of further studies are available, a reasonable target for pulse oxygen saturation (SpO2 is 90 to 93% with an intermittent review of the correlation between SpO2 and the partial pressure of arterial oxygen tension (PaO2. Because optimal oxygenation depends on individuals at the bedside making ongoing adjustments, each unit must define an optimal target range and set alarm limits according to their own equipment or conditions. All staff must be aware of these values and adjust the concentration of supplemental oxygen frequently.

    Full Text Available Background/Aim. Hemodynamic stress is the leading cause of acute renal failure (ARF in premature neonates. Incidence of ARF in this population is between 8 and 24%. The aim of this study was to determine the frequency of presence of ARF in premature neonates, as well as its impact on their survival. Methods. A retrospective study of 114 premature neonates [(gestational age, GA less than 37 gestation weeks (gw] admitted to the Intensive Care Unit (ICU at the Pediatric Clinic, Institute of Child and Youth Healthcare of Vojvodina in 2007 was conducted. Serum creatinine, urea and bilirubine were determined on the 3rd day of life in 65 newborns who met inclusion criteria. ARF was diagnosed in 16 newborns (n=16/65; 25%. Results. The premature neonates with ARF had significantly lower GA [<28 gw - 8/16 (50% vs. 5/49 (10%; p < 0.05], birth weight (BW (1 265 g vs. 1615 g; p < 0.05 and systolic blood pressure (43.37 mm Hg vs. 52.7 mmHg; p < 0.05 than ones without ARF. Non-olyguric ARF was diagnosed in 62% of newborns with ARF (n=10/16, while the rest had the olyguric type (n = 6/16; 38%. Twenty-five percent of premature neonates with ARF (n = 4/16 died in contrast to 10% of premature neonates without ARF (n = 5/49. ARF was treated conservatively in all but 3 cases when peritoneal dialysis was performed. Renal function has recovered completely in all of the survivors. In order to determine their predictivity in relation to ARF, following parameters were analyzed: GA, BW < 1 500 g, presence of concomitant sepsis and intracranial hemorrhage grade III/IV. BW < 1 500 g demonstrated the highest sensitivity (se 0.75, while GA < 28 gw, sepsis and intracranial hemorrhage grade III/IV showed high specificity (sp = 0.90, 0.89 0.88, respectively. Conclusion. Acute renal failure frequently occurs in population of premature neonates and requires meticulous fluid and electrolyte balance, especially in the case of low birth weight and extreme immaturity.

    Infants born preterm are at a higher risk of complications and hospitalization in cases of rotavirus diarrhea than children born at term. We evaluated the impact of a rotavirus vaccination campaign (May 2007 to May 2010) on hospitalizations for rotavirus gastroenteritis in a population of children under 3 years old born prematurely (before 37 weeks of gestation) in the Brest University Hospital birth zone. Active surveillance from 2002 to 2006 and a prospective collection of hospitalizations for rotavirus diarrhea were initiated in the pediatric units of Brest University Hospital until May 2010. Numbers of hospitalizations for rotavirus diarrhea among the population of children born prematurely, before and after the start of the vaccination program, were compared using a Poisson regression model controlling for epidemic-to-epidemic variation. A total of 217 premature infants were vaccinated from 2007 to 2010. Vaccine coverage for a complete course of three doses was 41.9%. The vaccine safety in premature infants was similar to that in term infants. The vaccination program led to a division by a factor of 2.6 (95% confidence interval [CI], 1.3 to 5.2) in the number of hospitalizations for rotavirus diarrhea during the first two epidemic seasons following vaccine introduction and by a factor of 11 (95% CI, 3.5 to 34.8) during the third season. We observed significant effectiveness of the pentavalent rotavirus vaccine on the number of hospitalizations in a population of prematurely born infants younger than 3 years of age. A multicenter national study would provide better assessment of this impact.

    The purpose of this longitudinal qualitative descriptive study was to explore American Indian (AI) mothers’ perceptions of parenting their premature infants over their first year of life in the context of their culture, including the birth and hospitalization experience. A convenience sample of 17 AI mothers and their premature infants were recruited from either a neonatal intensive care unit (NICU) or pediatric clinic in the southeast. Semistructured interviews were conducted at two time points. Through content analytic methods, three broad categories were revealed: descriptions of having a premature infant in the NICU, descriptions of parenting a premature infant, and the influence of Lumbee culture on parenting a premature infant. Certain aspects of AI culture appear to be important in having a premature infant in the NICU and in parenting a premature infant. We recommend that healthcare providers deliver culturally appropriate care that fully supports AI mothers and their premature infants. PMID:25721716

A convenience sample of 17 American Indian mothers and their premature infants were recruited from either a neonatal intensive care unit (NICU) or pediatric clinic in the southeast. Semistructured interviews were conducted at two time points. Through content analytic methods, three broad categories were revealed: descriptions of having a premature infant in the NICU, descriptions of parenting a premature infant, and the influence of Lumbee culture on parenting a premature infant. Certain aspects of American Indian culture appear to be important in having a premature infant in the NICU and in parenting a premature infant. We recommend that health care providers deliver culturally appropriate care that fully supports American Indian mothers and their premature infants. © The Author(s) 2015.

    Full Text Available Kate D Linton, Kevan R WylieSheffield Teaching Hospitals, Sheffield, UKAbstract: Premature ejaculation (PE is the most common sexual problem affecting men. It can affect men at all ages and has a serious impact on the quality of life for men and their partners. Currently there are no pharmaceutical agents approved for use in the UK, and so all drugs used for this condition are off label. Behavioral therapy has been used to treat PE, but the results are not durable once therapy has been concluded. Several topical therapies have been used including severance-secret (SS cream, lignocaine spray, lidocaine-prilocaine cream and lidocaine-prilocaine spray (TEMPE. There has been recent interest in the selective serotonin reuptake inhibitors (SSRIs for the treatment of PE, due to the fact that one of their common side effects is delayed ejaculation. Currently used SSRIs have several non-sexual side effects and long half lives, therefore there has been interest in developing a short acting, efficacious SSRI that can be used on-demand for PE. Dapoxetine has been recently evaluated for the treatment of PE by several groups, and results so far appear promising.Keywords: premature ejaculation, topical therapies, selective serotonin re-uptake inhibitor, dapoxetine

  10. Functional vision assessment of a premature child with congenital blindness

    Full Text Available In the program of early intervention in occupational therapy, the assessment of functional vision and infant development of children with visual impairment contributes to improve the development of their skills. The aim of this study was to present the results of the functional vision assessment of a premature child with congenital blindness and point out the importance of the findings for planning occupational therapy intervention and family orientation. The study participant was a preterm child with 6 months of corrected age and ophthalmological diagnosis of retinopathy of prematurity; she participated in the Visually Impaired Habilitation and Rehabilitation Program at a public university in the countryside of Sao Paulo state. For data collection, we used the Assessment of Functional Vision and Infant Development, an evaluation script that enables the record of children’s performance and behavior in response to different visual stimuli. We verified that, through the functional vision assessment, it is possible to learn the conditions that contribute to children’s ability to use their visual functioning and remaining sensory resources, pointing out the importance of material and environmental adaptations that favor children’s interaction with the external environment. The findings are relevant to aid in educating parents about children’s skills and understanding the different ways to encourage the use of functional vision in daily activities. Thus, the functional vision assessment of children with visual impairment is a relevant guiding parameter to complement the psychomotor development assessment in occupational therapy intervention.

    This study aimed to analyze the process of pain identification in premature by the professional staff of the Neonatal Intensive Care Unit of a public hospital in the interior of Bahia, Brazil. This is a quantitative descriptive exploratory study that was made through a form applied to twenty-four health professional of a Neonatal Intensive Care Unit. The data were analyzed in the Statistical Package for Social Sciences. The results showed 100% of professionals believed that newborns feel pain, 83.3% knew the pain as the fifth vital sign to be evaluated; 54,8% did not know the pain assessment scales; 70.8% did not use scales and highlighted behavioral and physiological signs of the newborn as signs suggestive of pain. Thus, it is important that professionals understand the pain as a complex phenomenon that demands early intervention, ensuring the excellence of care.

    Premature ovarian failure (POF) is a common condition, affecting approximately 1:100 women. It is characterised by amenorrhea, hypoestrogenism, and elevated gonadotrophin levels in women under the age of 40. It is often an unexpected and distressing diagnosis, which coincides with infertility and menopausal symptoms. There is a well recognised genetic basis to the development of POF. Our laboratory has identified several candidate genes associated with POF.

    Full Text Available Background: Premature birth is a major cause of infant mortality in developed countries. Newborns confined to neonatal intensive care units (NICUs are in a rapid stage of brain development. As such, sleep plays a pivotal role in the proper brain development of newborns. However, this developmental aspect is often disregarded due to the lack of information. Aim: This study aimed to evaluate the effect of nest posture on the sleep-wake state of premature infants. Method: This cross-over clinical trial was conducted on 60 premature infants admitted in the NICU of Ghaem Hospital in Mashhad, Iran in 2015. Infants were divided into two groups of experimental and control. Data were collected using the Assessment of Premature Infants' Behavior (APIB. Neonates in the control group were placed in an incubator, and neonates in the experimental group were positioned in a nest. Between-group comparison was performed using paired-samples T-test for normal variables and Wilcoxon test for non-normal variables. Results: In this study, no statistically significant differences were observed between the two groups in terms of the scores of deep sleep state before (P=0.50 and after the intervention (P=0.59. However, during the intervention, mean score of deep sleep was higher in the experimental group (P=0.08. Moreover, mean score of slow wake state had no significant difference between the study groups before (P=0.67, after (P=0.86, and during the intervention (P=0.81. Implications for Practice: According to the results of this study, nest posture increased the deep sleep hours of premature infants as the most imperative state of brain development. Therefore, it is recommended that nest posture be used to improve the deep sleep state of premature infants.

    1981-02-01

    Risk of premature birth was evaluated retrospectively in 610 women in the first days after delivery using the prematurity risk score published by Thalhammer 1973. The calculated risk of premature birth was compared than prospectively to postpartal morbidity of the newborn infants as determined by duration of hospital stay, incidence of respiratory distress syndrome, need of artificial ventilation and mortality. A positive correlation could be found between risk of premature birth and postpartal morbidity of the newborn infants especially in small premature infants with birthweights of 2000 grams and less. The same correlation existed also in two groups of infants out of two different obstetric clinics which showed the same distribution of prenatal risks and the same prenatal care frequencies. It clearly becomes evident that infants with the same prenatal risks but good prenatal care during pregnancy had much lower hospital stays, lower respiratory distress frequencies and lower mortality rates than babies delivered from pregnancies badly cared for. These prenatal care related differences in postpartum morbidity again were much more evident in infants out of lower birth weight classes.

    BACKGROUND: The beginning of the research on early interventions of premature and low birth body mass infants was a bit late. Evaluations on the effects of early interventions were just done at 1 year old or after 1 year old.OBJECTIVE: To discuss the effects of early interventions on infancy behavior development in premature and low birth weight infants.DESIGN: Randomized case-control trial study.SETTING, PARTICIPANTS and INTERVENTION: Sixty cases of premature and low birth body infants were chosen from Second Affiliated Hospital of Nanjing Medical University and were randomly divided into experimental group and control group. The experimental group included 16 males and 14 females, the mean body mass at birth was(2 268 +531) g. In the control group, there were also 16 males and 14 females, the mean body mass at birth was(2 307 + 398) g. A set of early stage upbringing plan designed by Professors Chen RH and Deng JY of Nanjing Medical University, which targeted for 0 to 3-year-old children was applied. The parents of the control group would go to early education clinic to learn how to train children by the doctor's instruction when the infants were born and in the 1st, 3rd, 6th, 9th, 12thmonth after birth. It was required that the parents should complete the training tasks of everyday, at the same time, the growth of physical build as well as the development of behaviors should be followed up and monitored.MAIN OUTCOME MEASURES: Development quotients in the 3rd, 6th, 9thand 12th month of both experimental and control groups.RESULTS: The average values of five developmental quotients in adaptability, gross motor, fine motor, language and sociability in the experimentalgroup were higher than those in the control group. Moreover, there were statistical differences in fine motor and social communication between the two groups from the 3nd month. When in the 12th month, there were significant differences in adaptability(97 +5, 89 +4), fine motor(98 + 10, 88 ± 8

    Objective: A large Danish birth cohort was used to test the independent and joint effects of perinatal measures associated with premature birth as predictors of the development of alcoholism in male and female subjects. Method: Subjects were born at the Copenhagen University Hospital between 1959 and 1961 (N = 9,125). A comprehensive series of measures was obtained for each of the 8,109 surviving and eligible infants before birth, during birth, shortly after birth, and at 1 year. The adult alcoholism outcome was defined as any ICD-10 F10 diagnosis (Mental and behavioral disorders due to alcohol use) or an equivalent ICD-8 diagnosis found in the Danish Psychiatric Central Research Register or the Municipal Alcohol Clinics of Copenhagen by 2007. Results: Multiple perinatal markers of premature birth independently predicted the development of an alcoholism diagnosis in male (n = 310) but not female (n = 138) subjects. Logistic regression modeling with a global prematurity score, adjusted for social status, maternal smoking, and gender, indicated a significant association of prematurity score for males (p premature birth are associated with gender-specific effects on the development of alcoholism in the male baby: small, premature, or growth-delayed male babies appear to be selectively vulnerable to alcoholic drinking years later. The findings implicate neurodevelopmental influences in alcoholism pathophysiology in males and suggest the possibility of distinct, gender-specific pathways in the etiology of severe problem drinking.

    Directory of Open Access Journals (Sweden)

    Wendelin Wolf

    Full Text Available The equipment of the plasma membrane in Saccharomyces cerevisiae with specific nutrient transporters is highly regulated by transcription, translation and protein trafficking allowing growth in changing environments. The activity of these transporters depends on a H(+ gradient across the plasma membrane generated by the H(+-ATPase Pma1. We found that the polytopic membrane protein Ist2 in the cortical endoplasmic reticulum (ER is required for efficient leucine uptake during the transition from fermentation to respiration. Experiments employing tandem fluorescence timer protein tag showed that Ist2 was necessary for efficient trafficking of newly synthesized leucine transporter Bap2 from the ER to the plasma membrane. This finding explains the growth defect of ist2Δ mutants during nutritional challenges and illustrates the important role of physical coupling between cortical ER and plasma membrane.

    2010-03-01

    Premature menopause affects 1% of women under the age of 40, the usual age of the menopause is 51. Most women will present with irregular periods or no periods at all with or without climacteric symptoms. Around 10% of women present with primary amenorrhoea. A careful history and examination are required. It is important to ask specifically about previous chemotherapy or radiotherapy and to look for signs of androgen excess e.g. polycystic ovarian syndrome, adrenal problems e.g. galactorrhoea and thyroid goitres. Once pregnancy has been excluded, a progestagen challenge test can be performed in primary care. Norethisterone 5 mg tds po for ten days or alternatively medroxyprogesterone acetate 10 mg daily for ten days is prescribed. A withdrawal bleed within a few days of stopping the norethisterone indicates the presence of oestrogen and bleeding more than a few drops is considered a positive withdrawal bleed. The absence of a bleed indicates low levels of oestrogen, putting the woman at risk of CVD and osteoporosis. FSH levels above 30 IU/l are an indicator that the ovaries are failing and the menopause is approaching or has occurred. It should be remembered that FSH levels fluctuate during the month and from one month to the next, so a minimum of two measurements should be made at least four to six weeks apart. The presence of a bleed should not exclude premature menopause as part of the differential diagnosis as there can be varying and unpredictable ovarian function remaining. The progestagen challenge test should not be used alone, but in conjunction with FSH, LH and oestradiol. There is no treatment for premature menopause. Women desiring pregnancy should be referred to a fertility clinic and discussion of egg donation. Women not wishing to become pregnant should be prescribed HRT until the age of 50 to control symptoms of oestrogen deficiency and reduce the risks of osteoporosis and CVD.

  12. The pathophysiology of lifelong premature ejaculation.

    Waldinger, Marcel D

    2016-08-01

    For many decades it has been thought that lifelong premature ejaculation (PE) is only characterized by persistent early ejaculations. Despite enormous progress of in vivo animal research, and neurobiological, genetic and pharmacological research in men with lifelong PE, our current understanding of the mechanisms behind early ejaculations is far from complete. The new classification of PE into four PE subtypes has shown that the symptomatology of lifelong PE strongly differs from acquired PE, subjective PE and variable PE. The phenotype of lifelong PE and therefore also the pathophysiology of lifelong PE is much more complex. A substantial number of men with lifelong PE not only have PE, but also premature erection and premature penile detumescence as part of an acute hypertonic or hypererotic state when engaged in an erotic situation or when making love. As both erectio praecox, ejaculatio praecox, detumescentia praecox, and the hypererotic state are part of the phenotype lifelong PE, it is argued that lifelong PE is not only a disturbance of the timing of ejaculation but also a disturbance of the timing of erection, detumescence and arousal. Since 1998, the pathophysiology of lifelong PE was thought to be mainly mediated by the central serotonergic system in line with genetic polymorphisms of specific serotonergic genes. However, by accepting that lifelong PE is characterized by the reversible hypertonic state the hypothesis of mainly serotonergic dysfunction is no longer tenable. Instead, it has been postulated that the pathophysiology of lifelong PE is mediated by a very complex interplay of central and peripheral serotonergic, dopaminergic, oxytocinergic, endocrinological, genetic and probably also epigenetic factors. Progress in research of lifelong PE can only be accomplished when a stopwatch is used to measure the IELT and the cut-off point of 1 minute for the definition of lifelong PE is maintained.

  15. Lowering the premature birth rate: what the U.S. experience means for Japan.

    Science.gov (United States)

    Noguchi, Akihiko

    2008-03-01

    Premature birth rate and low birth weight rate are increasing in industrialized countries including USA and Japan. The Infant mortality rate (IMR) is three times and 50-75 times greater for infants born at 32-36 weeks and Premature birth is heterogeneous in origin and idiopathic in 70% of the cases. Increased utilization of assisted reproductive technology only accounts for a part of the recent trend. Evidence suggests environmental factors play a significant role, and genetic-environmental interaction is plausible. A chronic psychosocial stress of pregnant women has been postulated to be modifying the endocrine milieu thereby influencing pregnancy outcomes. In a preliminary observation in St. Louis, homeless pregnant women with high behavioral and social risks, when accommodated in a shelter home designed for these women, produced significantly less numbers of premature and low birth weight infants as compared with the general population. Furthermore, in a randomized controlled study in Washington DC, psychobehavioral intervention specifically targeting smoking (primary and secondary), intimate partner violence (IPV), and depression among black pregnant women significantly decreased the rate of miscarriage and low birth weight. These reports may have significant implication to the Japanese situation. Increasing number of Japanese women at reproductive age are exposed to smoking, may have underling psychosocial stress and may suffer from subclinical depression and/or from IPV. Detailed epidemiological studies of women before and during the reproductive age with regard to risk factors can lead to an effective intervention strategy against premature birth in Japan.

    This study evaluated the prevalence of enamel defects and dental caries and their risk factors on primary and permanent dentitions of prematurely-born children and term children. Eighty children were examined, 40 born prematurely (G1) and 40 born term (G2), in the age group between 5 and 10 years. The demographic variables, medical history and oral health behaviors were recorded on a questionnaire. The teeth were examined for presence of deficiencies of the enamel and caries that were registered. The caries were registered, focusing on the indices dmft (decayed, missing, and filled primary teeth) and DMFT (decayed, missing, and filled permanent teeth). The results showed that 75% of the total sample had enamel defects. The logistic regression model showed that other risk factors such as per capita family income, educational level, dietary and hygiene habits, fluoride exposure, trauma, and diseases had no correlation with enamel defects and caries. A smaller value of total DMFT (0.95) was found in the group of premature children in comparison to the term children (2.07) p = 0.0164. There was no difference concerning the permanent dentition between the two groups (p = 0.9926). One concludes that prematurity can't be a predisposing factor for the presence of dental caries.

    Full Text Available Background: Fetal surgery is selectively offered for severe or life-threatening fetal malformations. These infants are often born prematurely and are thus at risk for retinopathy of prematurity (ROP. It is not known whether fetal surgery confers an increased risk of developing severe ROP relative to published rates in standard premature populations ≤37 weeks of age grouped by birth weight (

    Increasing rates of preterm births coupled with better survival of these infants have resulted in higher prevalence of systemic and ocular complications associated with prematurity. In addition to retinopathy of prematurity, infants who are born preterm may suffer from severe visual impairment as a result of hypoxic ischemic encephalopathy, hypoglycemia, and other metabolic imbalances. The effect of these processes on the anterior visual pathway may result in optic atrophy, optic nerve hypoplasia or optic disc cupping and affection of the posterior visual pathway leads to cortical visual impairment (CVI). Other ocular associations include strabismus, nystagmus, and ocular motor abnormalities such as tonic down gaze and defective saccades and pursuits. Cortical and subcortical involvement also manifests as defects in functional vision and these have not yet been completely understood. Children with CVI may have visual field defects, photophobia, defective visual processing, and deficient color vision. Since most of these children also suffer from additional systemic disabilities, evaluation, and management remains a challenge. However, early diagnosis and initiation of rehabilitation therapy can prove to be of significant benefit in these children.

    Nazar, N

    This work is the product of the checking of the pathogenesis, incidence, treatment, and prognostic of the intraventricular hemorrhage in the premature newborn. In the revised publications, that include important series of following, this pathology is present in 25% of the infants weighing less than 1,500 g, in which the mortality and morbidity is greater than that of normal newborns, since the development of intraventricular hemorrhage can produce alterations of cerebral blood flow in the immature germinal matrix and in the microvascular net. In consequence the prevention of the intraventricular hemorrhage is directly related with its pathogenesis. It is said that the use of dexamethasone steroids in low doses in the prenatal period, and low doses of indomethacin in the postnatal period, can give better neuroprotection. The surgical treatment is exceptional and has very precise indications, when a progresive hydrocephalus of later apparition is proven. Therefore in premature newborns with intraventricular hemorrhage the best actual treatment is to use an appropiate pharmacological and medical following

    The second Ad Hoc International Society for Sexual Medicine (ISSM) Committee for the Definition of Premature Ejaculation defined acquired premature ejaculation (PE) as a male sexual dysfunction characterized by a the development of a clinically significant and bothersome reduction in ejaculation latency time in men with previous normal ejaculatory experiences, often to about 3 minutes or less, the inability to delay ejaculation on all or nearly all vaginal penetrations, and the presence of negative personal consequences, such as distress, bother, frustration and/or the avoidance of sexual intimacy. The literature contains a diverse range of biological and psychological etiological theories. Acquired PE is commonly due to sexual performance anxiety, psychological or relationship problems, erectile dysfunction (ED), and occasionally prostatitis and hyperthyroidism, consistent with the predominant organic etiology of acquired PE, men with this complaint are usually older, have a higher mean BMI and a greater incidence of comorbid disease including hypertension, sexual desire disorder, diabetes mellitus, chronic prostatitis, and ED compared to lifelong, variable and subjective PE.

  2. Premature ovarian insufficiency: Pathogenesis and management

    2015-01-01

    Full Text Available The term premature ovarian insufficiency (POI describes a continuum of declining ovarian function in a young woman, resulting in an earlier than average menopause. It is a term that reflects the variable nature of the condition and is substantially less emotive than the formerly used "premature ovarian failure" which signaled a single event in time. Contrary to the decline in the age of menarche seen over the last 3-4 decades there has been no similar change in the age of menopause. In developed nations, the average age for cessation of menstrual cycles is 50-52 years. The age is younger among women from developing nations. Much has been written about POI despite a lack of good data on the incidence of this condition. It is believed that 1% of women under the age of 40 years and 0.1% under the age of 30 years will develop POI. Research is increasingly providing information about the pathogenesis and treatments are being developed to better preserve ovarian function during cancer treatment and to improve fertility options. This narrative review summarizes the current literature to provide an approach to best practice management of POI.

    Full Text Available This report deals with our experience in the management of threshold retinopathy of prematurity (ROP. A total of 45 eyes of 23 infants were subjected to treatment of threshold ROP. 26.1% of these infants had a birth weight of >l,500 gm. The preferred modality of treatment was laser indirect photocoagulation, which was facilitated by scleral depression. Cryopexy was done in cases with nondilating pupils or medial haze and was always under general anaesthesia. Retreatment with either modality was needed in 42.2% eyes; in this the skip areas were covered. Total regression of diseases was achieved in 91.1% eyes with no sequelae. All the 4 eyes that progressed to stage 5 despite treatment had zone 1 disease. Major treatment-induced complications did not occur in this series. This study underscores the importance of routine screening of infants upto 2,000 gm birth weight for ROP and the excellent response that is achieved with laser photocoagulation in inducing regression of threshold ROP. Laser is the preferred method of treatment in view of the absence of treatment-related morbidity to the premature infants.

    In September 2010, the first International Scientific Tendinopathy Symposium (ISTS) was held in Umeå, Sweden, to establish a forum for original scientific and clinical insights in this growing field of clinical research and practice. The second ISTS was organised by the same group and held in Vancouver, Canada, in September 2012. This symposium was preceded by a round-table meeting in which the participants engaged in focused discussions, resulting in the following overview of tendinopathy clinical and research issues. This paper is a narrative review and summary developed during and after the second ISTS. The document is designed to highlight some key issues raised at ISTS 2012, and to integrate them into a shared conceptual framework. It should be considered an update and a signposting document rather than a comprehensive review. The document is developed for use by physiotherapists, physicians, athletic trainers, massage therapists and other health professionals as well as team coaches and strength/conditioning managers involved in care of sportspeople or workers with tendinopathy.

    The endosomal sorting complex required for transport (ESCRT) machinery is responsible for membrane remodeling in a number of biological processes including multivesicular body biogenesis, cytokinesis, and enveloped virus budding. In mammalian cells, efficient abscission during cytokinesis requires proper function of the ESCRT-III protein IST1, which binds to the microtubule interacting and trafficking (MIT) domains of VPS4, LIP5, and Spartin via its C-terminal MIT-interacting motif (MIM). Here, we studied the molecular interactions between IST1 and the three MIT domain-containing proteins to understand the structural basis that governs pairwise MIT-MIM interaction. Crystal structures of the three molecular complexes revealed that IST1 binds to the MIT domains of VPS4, LIP5, and Spartin using two different mechanisms (MIM1 mode versus MIM3 mode). Structural comparison revealed that structural features in both MIT and MIM contribute to determine the specific binding mechanism. Within the IST1 MIM sequence, two phenylalanine residues were shown to be important in discriminating MIM1 versus MIM3 binding. These observations enabled us to deduce a preliminary binding code, which we applied to provide CHMP2A, a protein that normally only binds the MIT domain in the MIM1 mode, the additional ability to bind the MIT domain of Spartin in the MIM3 mode. © 2015 by The American Society for Biochemistry and Molecular Biology, Inc.

    Full Text Available In den letzten Jahren haben Leitlinien in der Praxis der klinischen Medizin eine dominierende Rolle übernommen, manche von ihnen wurden sogar in gesundheitspolitische Vorgaben übernommen. Die Basis der Leitlinien bilden vor allem Ergebnisse aus randomisierten kontrollierten Studien (RCTs, die in der Rangliste der Evidenz weit über der persönlichen Meinung des Arztes rangieren. Während allerdings Leitlinien das Wohl der Gruppe im Auge haben, ist der Arzt mit individuellen Patienten konfrontiert, bei denen die leitliniengetriebene Medizin nicht immer zum besten Ergebnis führt. Wenn nun strenge Vorgaben eine von der Leitlinie abweichende Haltung massiv erschweren, entsteht ein Spannungsfeld, welches oft reflexartig zu einer Ablehnung der „evidence based medicine“ (EBM führt. In der Analyse von RCTs geht man davon aus, dass das mittlere Verhalten der untersuchten Population das einzelne Individuum gut repräsentiert, dies wird von Anhängern der „personalisierten“ Medizin (PM vehement bestritten. Ein Kompromiss wäre es zu versuchen, unsere Patienten viel besser als bisher zu charakterisieren, bevor sie in RCTs eingeschlossen werden. Dies könnte die Distanz zwischen EBM und PM reduzieren und so auf der einen Seite einen diagnostischen und therapeutischen „Wildwuchs“ verhindern, auf der anderen aber einen stärker individualisierten Zugang in der klinischen Medizin ermöglichen.

    Temperament is the first distinct and stable personality after infants' birth. The development and type of the temperament is mainly associated with genetics factors, premature birth, low birth weight and clinical complications. This article describes the domestic and abroad researches and progress on premature infants' temperament in recent years, including research methods, temperament characteristic and influence factors of temperament types, and emphersizes the importance of the study on the premature infants' temperament. We raise the point that analyzing the temperament of premature children in early stage could discover temperament disorders earlier, and guide targeted training or behavior education based on different temperaments, which do good to intelligence and psychological development of premature infants.%气质是婴儿出生后最早表现出来的较为明显而稳定的人格特征,遗传、早产、低出生体质量以及与早产相关的临床并发症对气质的发展和类型有重要影响.该文通过总结近年来国内外早产儿气质研究的成果和进展,综述了早产儿气质研究的研究方法、早产儿气质特点及气质类型的影响因素,强调早产儿气质研究的重要性,提出对早产儿进行气质分析可以早期发现问题,循序渐进地对不同气质儿童进行针对性培养和行为教育,有助于早产儿智能和心理的健康发育.

    Full Text Available Premature rupture of membranes (PROM is one of the most common complications of pregnancy that has a major impact on neonatal outcomes. With respect to racial, nutritional and cultural differences between developed and developing countries, this study was conducted to detect the prevalence of neonatal complications following PROM and the role of the duration of rupture of membranes in producing morbidities and mortalities in these neonates in our hospital. Among 2357 pregnant women, we found 163 (6.91% cases of premature rupture of the fetal membranes in Tehran Vali-e-Asr Hospital during April 2001 to April 2002. Route of delivery was cesarean section in 65.6% of women. Urinary tract infection occured in 1.8%, maternal leukocytosis and fever in 20.2% and 5.5%, chorioamnionitis in 6.1%, fetal tachycardia in 1.2% and olygohydramnios in 4.9%. Gestational age in 138 (86% of neonates was less than 37 completed weeks. Thirty five infants (21.47% had respiratory distress syndrome and 33 (20.245% had clinical sepsis. Pneumonia in 6 (3.7% and skeletal deformity in 7 (4.294% were seen. Rupture of membrane of more than 24 hours duration occurred in 71 (43.6% of the patients. Comparison of morbidities between two groups of neonates and their mothers according to the duration of PROM (less and more than 24 hours showed significant differences in NICU admission, olygohydramnios, maternal fever, leukocytosis and chorioamnionitis rates (p24 hr of PROM with an odds ratio of 2.68 and 2.73, respectively. Positive blood and eye cultures were detected in 16 cases during 72 hours of age. Staphylococcus species, klebsiella, E.coli and streptococcus were the predominant organisms among positive blood cultures. Mortality was seen in 18 (11% of neonates because of respiratory failure, disseminated intravascular coagulation, septic shock, and a single case of congenital toxoplasmosis.

    Brain ultrasonography plays a central role in the detection and management of neonatal disease in the preterm infant. Although morphological study, using high-frequency transducers, remains the cornerstone of imaging, pulsed and colour Doppler scans provide additional information and improve the diagnostic and prognostic accuracy of ultrasonography. Particular features of normal brain US in the extremely preterm infant are reported. Cerebral haemorrhage and its different patterns (intraventricular haemorrhage and periventricular hemorrhagic infarction) are described. The value of Doppler techniques is emphasized, e.g. demonstration of coloured signal within the aqueduct of Sylvius, visualization of patency of the terminal veins, demonstration of Doppler spectrum fluctuations, recognition of low blood flow, and the detection of vasodilatation. The sonographic diagnosis of periventricular leucomalacia and its difficulties are documented. Some uncommon brain lesions of the premature infant are illustrated, e.g. gangliothalamic ischaemic damage, cortical necrosis, focal infarcts, etc. The importance of repeating the US examinations until near term is highlighted.

    Full Text Available Premature ovarian failure (POF is a condition affecting 1-2% of women younger than 40 years of age, characterized by amenorrhea, hypoestrogenism and elevated gonadotropin levels. In the last years it became a problem of social health interest as the frequency increased due to environmental factors and new, efficient methods for cancer treatment in young women. Few genes have beed identified to explain cases of POF but there are also autoimmune associated conditions and an increasing number of iatrogenic cases (chemotherapy, surgery, radiotherapy. Modern approach in POF means not only a precise etiological diagnosis, but also a correct counseling for these patients who often want to become parents, and a chance for a healthy life without the long term consequences of estrogen deprivation from an early age. In vitro fertilization (IVF techniques can be useful for certain cases but research is needed on strategies to improve fertility for women who have follicles remaining in the ovaries.

    2009-01-01

    Premature birth is a growing and significant public health problem because of the large number of infants that survive with neurodevelopmental sequelae from brain injury. Recent advances in neuroimaging have shown that although some neuroanatomical structures are altered, others improve over time. This review outlines recent insights into brain structure and function in these preterm infants at school age and relevant animal models. These animal models have provided scientists with an opportunity to explore in depth the molecular and cellular mechanisms of injury as well as the potential of the brain for recovery. The endogenous potential that the brain has for neurogenesis and gliogenesis, and how environment contributes to recovery, are also outlined. These preclinical models will provide important insights into the genetic and epigenetic mechanisms responsible for variable degrees of injury and recovery, permitting the exploration of targeted therapies to facilitate recovery in the developing preterm brain.

    2011-09-01

    Full Text Available Gastric pneumatosis is extremely rare during infancy. It has been reported in association with necrotizing enterocolitis or congenital abnormalities such as pyloric stenosis. Here, we report a case of gastric pneumatosis in a premature neonate on synchronized nasal intermittent positive pressure ventilation. No pneumatosis was noted in the rest of the bowel or esophagus. There could have been mild damage in the gastric mucosa, either related to the placement of the feeding tube or secondary to the use of indomethacin or both. The condition was further aggravated by noninvasive ventilation. An increase in intragastric pressure resulted in the submucosal dissection of air followed by the development of gastric pneumatosis. Conservative management strategies, including the use of a nasogastric tube for decompression and the withholding of feeding, successfully managed the gastric pneumatosis in our patient. An uneventful recovery was made after conservative management. Prompt recognition and evaluation of this condition were essential for making the diagnosis.

    2016-08-01

    Premature ejaculation (PE) is a poorly understood condition and is considered as the most common sexual disorder in men. The ambiguity surrounding PE is in part due to the difficulty in conducting and interpreting research in the absence of a standardised definition that adequately encompasses the characteristics of these patients. An enhanced awareness of sexual dysfunctions in the recent decades has lead to an increase in scientific research that has challenged the traditional paradigm regarding PE. This has also enabled to establish a universal definition and classification of the disease. A move to a more evidence based approach has improved the clinicians' ability to define those who need medical treatment, as well as perform further research in this complex condition.

  20. Bmi-1 absence causes premature brain degeneration.

    Directory of Open Access Journals (Sweden)

    Guangliang Cao

    Full Text Available Bmi-1, a polycomb transcriptional repressor, is implicated in cell cycle regulation and cell senescence. Its absence results in generalized astrogliosis and epilepsy during the postnatal development, but the underlying mechanisms are poorly understood. Here, we demonstrate the occurrence of oxidative stress in the brain of four-week-old Bmi-1 null mice. The mice showed various hallmarks of neurodegeneration including synaptic loss, axonal demyelination, reactive gliosis and brain mitochondrial damage. Moreover, astroglial glutamate transporters and glutamine synthetase decreased in the Bmi-1 null hippocampus, which might contribute to the sporadic epileptic-like seizures in these mice. These results indicate that Bmi-1 is required for maintaining endogenous antioxidant defenses in the brain, and its absence subsequently causes premature brain degeneration.

    2010-04-01

    The pacemaking system of the heart is complex; a healthy heart constantly integrates and responds to extracardiac signals, resulting in highly complex heart rate patterns with a great deal of variability. In the laboratory and in some pathological or age-related states, however, dynamics can show reduced complexity that is more readily described and modeled. Reduced heart rate complexity has both clinical and dynamical significance - it may provide warning of impending illness or clues about the dynamics of the heart's pacemaking system. In this paper, we describe simple and interesting heart rate dynamics that we have observed in premature human infants - reversible transitions to large-amplitude periodic oscillations - and we show that the appearance and disappearance of these periodic oscillations can be described by a simple mathematical model, a Hopf bifurcation.

  2. Enteral nutrition of the premature infant

    Directory of Open Access Journals (Sweden)

    Su Jin Cho

    2010-01-01

    Full Text Available Early nutritional support for preterm infants is critical because such support influences long-term outcome. Minimal enteral feeding should be initiated as soon as possible if an infant is stable and if feeding advancement is recommended as relevant to the clinical course. Maternal milk is the gold standard for enteral feeding, but fortification may be needed to achieve optimal growth in a rapidly growing premature infant. Erythromycin may aid in promoting gastrointestinal motility in cases that exhibit feeding intolerance. Selected preterm infants need vitamins, mineral supplements, and calorie enhancers to meet their nutritional needs. Despite all that is known about this topic, additional research is needed to guide postdischarge nutrition of preterm infants in order to maintain optimal growth and neurodevelopment.

  3. Premature and accelerated ageing: HIV or HAART?

    Directory of Open Access Journals (Sweden)

    Reuben Luke Smith

    2013-01-01

    Full Text Available Highly Active Anti-Retroviral Therapy (HAART has significantly increased life expectancy of the HIV-positive population. Nevertheless, the average lifespan of HIV patients remains shorter compared to uninfected individuals. Immunosenescence, a current explanation for this difference invokes heavily on viral stimulus despite HAART efficiency in viral suppression. We propose here that the premature and accelerated ageing of HIV patients can also be caused by adverse effects of antiretroviral drugs, specifically those that affect the mitochondria. The Nucleoside Reverse Transcriptase Inhibitor (NRTI antiretroviral drug class for instance, is known to cause depletion of mitochondrial DNA via inhibition of the mitochondrial specific DNA polymerase-ƴ. Besides NRTIs, other antiretroviral drug classes such as Protease Inhibitors also cause severe mitochondrial damage by increasing oxidative stress and diminishing mitochondrial function. We also discuss important areas for future research and argue in favour of the use of C. elegans as a novel model system for studying these effects.

    Over the decades, medical staff have developed strategies to manage crying episodes of the critically ill and convalescing premature infant. These episodes of crying occur frequently after infants are removed from ventilation, but before they are able to receive nutrition orally. Not only are these episodes stressful to infants and upsetting to parents, but they are also stressful and time consuming for the staff that take care of these patients. Although the literature supports the benefits of music therapy in regard to physiological and certain behavioral measures with premature infants, no research exists that explores the use of music therapy with inconsolability related to the "nothing by mouth" status. This study explored the effects of music therapy on the crying behaviors of critically ill infants classified as inconsolable. Twenty-four premature infants with gestational age 32-40 weeks received a developmentally appropriate music listening intervention, alternating with days on which no intervention was provided. The results revealed a significant reduction in the frequency and duration of episodes of inconsolable crying as a result of the music intervention, as well as improved physiological measures including heart rate, respiration rate, oxygen saturation, and mean arterial pressure. Findings suggest the viability of using recorded music in the absence of a music therapist or the maternal voice to console infants when standard nursing interventions are not effective.

    Full Text Available Consumption Culture and Art Education: Cultural Compounds of Traditional Resistances and Futuristic Strategies In Postmodern(ist Art Education New cultural fields and definitions have begun to develop through the globalization of cultural policies. It is inevitable that pedagogical debates in reference to the culture contact with art education in a great level. While a cultural study is to have a connection with other fields, art education is thought to be fed by a dynamic forming a common ground between conditions of cultural fields and those of itself. It is likely to express plenty of contents to be referred to art education by regarding culture of consumption of culture and art as an axis. These contents consist of the following titles such as traditional, actual and futuristic assessments of culture, experience of consumption, aesthetic of consumption, contents of visual and social consumption, concepts of consumption in art and consumption motivations of postmodern individual. Therefore, it is required to consider that connection between consumption culture and art education is a content belonging to postmodern art education and will become a notable scope in prospective art education in view of strategic facts

    Buildings in the USA are commonly not perceived as energy efficient and sustainable. Considering this, it comes as a surprise that the LEED (Leadership in Energy and Environmental Design) certification system is leading the process to certify ''Green Buildings'' despite the broad range of certification systems in countries such as BREEAM in England, CASBEE in Japan, HQE in France, Green Star in Australia, and most recently DGNB in Germany. International companies are pursuing the LEED certification due to its worldwide applicability - over 20,000 buildings in 76 countries are currently registered.

  7. Mechanical ventilation of the premature neonate.

    Although the trend in the neonatal intensive care unit is to use noninvasive ventilation whenever possible, invasive ventilation is still often necessary for supporting pre-term neonates with lung disease. Many different ventilation modes and ventilation strategies are available to assist with the optimization of mechanical ventilation and prevention of ventilator-induced lung injury. Patient-triggered ventilation is favored over machine-triggered forms of invasive ventilation for improving gas exchange and patient-ventilator interaction. However, no studies have shown that patient-triggered ventilation improves mortality or morbidity in premature neonates. A promising new form of patient-triggered ventilation, neurally adjusted ventilatory assist (NAVA), was recently FDA approved for invasive and noninvasive ventilation. Clinical trials are underway to evaluate outcomes in neonates who receive NAVA. New evidence suggests that volume-targeted ventilation modes (ie, volume control or pressure control with adaptive targeting) may provide better lung protection than traditional pressure control modes. Several volume-targeted modes that provide accurate tidal volume delivery in the face of a large endotracheal tube leak were recently introduced to the clinical setting. There is ongoing debate about whether neonates should be managed invasively with high-frequency ventilation or conventional ventilation at birth. The majority of clinical trials performed to date have compared high-frequency ventilation to pressure control modes. Future trials with premature neonates should compare high-frequency ventilation to conventional ventilation with volume-targeted modes. Over the last decade many new promising approaches to lung-protective ventilation have evolved. The key to protecting the neonatal lung during mechanical ventilation is optimizing lung volume and limiting excessive lung expansion, by applying appropriate PEEP and using shorter inspiratory time, smaller tidal

    Delayed umbilical cord clamping is reported to increase neonatal blood volume. We estimated the clinical outcomes in premature neonates who had delayed umbilical cord clamping compared with a similar group who had early umbilical cord clamping. This was a before-after investigation comparing early umbilical cord clamping with delayed umbilical cord clamping (45 seconds) in two groups of singleton neonates, very low birth weight (VLBW) (401-1,500 g) and low birth weight (LBW) (greater than 1,500 g but less than 35 weeks gestation). Neonates were excluded from delayed umbilical cord clamping if they needed immediate major resuscitation. Primary outcomes were provision of delivery room resuscitation, hematocrit, red cell transfusions, and the principle Vermont Oxford Network outcomes. In VLBW neonates (77 delayed umbilical cord clamping, birth weight [mean±standard deviation] 1,099±266 g; 77 early umbilical cord clamping 1,058±289 g), delayed umbilical cord clamping was associated with less delivery room resuscitation, higher Apgar scores at 1 minute, and higher hematocrit. Delayed umbilical cord clamping was not associated with significant differences in the overall transfusion rate, peak bilirubin, any of the principle Vermont Oxford Network outcomes, or mortality. In LBW neonates (172 delayed umbilical cord clamping, birth weight [mean±standard deviation] 2,159±384 g; 172 early umbilical cord clamping 2,203±447 g), delayed umbilical cord clamping was associated with higher hematocrit and was not associated with a change in delivery room resuscitation or Apgar scores or with changes in the transfusion rate or peak bilirubin. Regression analysis showed increasing gestational age and birth weight and delayed umbilical cord clamping were the best predictors of higher hematocrit and less delivery room resuscitation. Delayed umbilical cord clamping can safely be performed in singleton premature neonates and is associated with a higher hematocrit, less delivery room

  9. Beryllium induces premature senescence in human fibroblasts.

    After cells have completed a sufficient number of cell divisions, they exit the cell cycle and enter replicative senescence. Here, we report that beryllium causes proliferation arrest with premature expression of the principal markers of senescence. After young presenescent human fibroblasts were treated with 3 microM BeSO(4) for 24 h, p21 cyclin-dependent kinase inhibitor mRNA increased by >200%. Longer periods of exposure caused mRNA and protein levels to increase for both p21 and p16(Ink4a), a senescence regulator that prevents pRb-mediated cell cycle progression. BeSO(4) also caused dose-dependent induction of senescence-associated beta-galactosidase activity (SA-beta-gal). Untreated cells had 48 relative fluorescence units (RFU)/microg/h of SA-beta-gal, whereas 3 microM BeSO(4) caused activity to increase to 84 RFU/microg/h. In chromatin immunoprecipitation experiments, BeSO(4) caused p53 protein to associate with its DNA binding site in the promoter region of the p21 gene, indicating that p53 transcriptional activity is responsible for the large increase in p21 mRNA elicited by beryllium. Forced expression of human telomerase reverse transcriptase (hTERT) rendered HFL-1 cells incapable of normal replicative senescence. However, there was no difference in the responsiveness of normal HFL-1 fibroblasts (IC(50) = 1.9 microM) and hTERT-immortalized cells (IC(50) = 1.7 microM) to BeSO(4) in a 9-day proliferation assay. The effects of beryllium resemble those of histone deacetylase-inhibiting drugs, which also cause large increases in p21. However, beryllium produced no changes in histone acetylation, suggesting that Be(2+) acts as a novel and potent pharmacological inducer of premature senescence.

    This paper presents several types of evolutionary algorithms (EAs) used for global optimization on real domains. The interest has been focused on multimodal problems, where the difficulties of a premature convergence usually occurs. First the standard genetic algorithm (SGA) using binary encoding of real values and its unsatisfactory behavior with multimodal problems is briefly reviewed together with some improvements of fighting premature convergence. Two types of real encoded methods based on differential operators are examined in detail: the differential evolution (DE), a very modern and effective method firstly published by R. Storn and K. Price, and the simplified real-coded differential genetic algorithm SADE proposed by the authors. In addition, an improvement of the SADE method, called CERAF technology, enabling the population of solutions to escape from local extremes, is examined. All methods are tested on an identical set of objective functions and a systematic comparison based on a reliable method...

    1993-08-01

    Premature ovarian failure (POF) in women is characterized as menopause commencing before age 35. Although some cases of POF appear to be inherited, no experimental animal models of familial POF are available. Recently a mouse mutation has been identified that results in infertility due to a lack of primordial germ cells arising in early embryonic development. It was observed that shortly after puberty, females homozygous for this mutation entered reproductive senescence as defined by high levels of circulating gonadotropins, inability to respond either hormonally or functionally to superovulation, and a disrupted estrous cycle. Also, the ovaries completely lacked developing follicles and the endometrium was inactive. However, these mice had undergone complete sexual development as determined by age of vaginal opening, mammary gland histology, and sexual behavior. Thus, these animals closely mimic familial premature ovarian failure and may be useful models for study of the pathogenesis and treatment of this condition.

    The identification and characteristics of premature convergence in genetic algorithms (GAs) are investigated Through a detailed quantitative analysis on the search capability and the degree of population diversity, the cause of premature convergence in GAs is recognized, and attributed to the maturation effect of the GAs: The minimum schema deduced from current population, which is the largest search space of a GA, converges to a homogeneous population in probability 1 ( so the search capability of the GA decreases and premature convergence occurs). It is shown that, as quantitative features of the maturation effect, the degree of population diversity converges to zero with probability 1, and the tendency for premature convergence is inversely proportional to the population size and directly proportional to the variance of the fitness ratio of zero allele at any gene position of the current population. Based on the theoretical analysis, several strategies for preventing premature convergence are suggest

    The studies on the aetiological factors of a premature delivery constitute an old fear of obstetricians and epidemiologists. However, they remain confused and the very definition of prematurity is among the first sources of confusion. There are many therapeutic methods considered as preventive. Their efficacy is debatable whilst their secondary effects are obvious. In this article, the authors report the results of a retrospective study of observations of patients who presented threats of premature labour and analyzed the epidemiological aspects, the aetiological factors and the therapeutic methods. It seems important to consider the risk factors in order to prevent premature labour. A decrease in the use of betamimetics and an increase in that of therapies said to be of replacement does not seem to be accompanied by a relative increase in the incidence of prematurity.

    2015-10-01

    Premature ejaculation is one of the most common sexual dysfunctions in men. Recent epidemiological studies suggest its prevalence in Australia may range from 21-31% This article will discuss the current definition of premature ejaculation from a urological perspective. It will provide an understanding of the pathogenesis of premature ejaculation, as well as assessment and management options. Premature ejaculation can have a significant adverse effect on the quality of life for the patient and his sexual partners. It can potentially lead to psychological distress, diminished self- esteem, anxiety, erectile dysfunction, reduced libido and poor interpersonal relationships. Most men feel reluctant to discuss premature ejaculation with their general practitioner despite its psychological, emotional and relational effects. Effective, evidence-based treatment options are available and physicians should feel confident when exploring ways to improve the quality of life for men with sexual dysfunction.

  4. Hypothyroxinemia of prematurity: rite of passage or therapeutic necessity?

    Science.gov (United States)

    Beeram, M R; Wilson, D P

    2000-11-01

    Hypothyroxinemia is a common finding in premature infants, presumably resulting from an immature hypothalamic-pituitary-thyroid axis. Because dynamic studies of thyroid function in premature infants are normal and the condition resolves spontaneously, HOP has been considered physiologic rather than pathologic. Thus, thyroid hormone supplementation has been assumed to be not required in premature infants. True hypothyroidism of hypothalamic pituitary or thyroid origin, however, does occur in premature as well as in term infants and should be investigated aggressively and treated appropriately. Current studies in premature infants with hypothyroxinemia suggest the following: infants with more than 27 weeks of gestation do not appear to benefit and may, in fact, be harmed by thyroid hormone supplementation; and short-term thyroid hormone supplementation in infants born before 27 weeks of gestation may be important to diminish morbidity and to improve neurodevelopmental outcome.

    Although both biological and psychological factors are important in the etiology, the exact pathogenesis of lifelong premature ejaculation (PE) remains to be clarified. Obesity is a worldwide epidemic that contributes to many chronic diseases. Obesity is associated with erectile dysfunction, but the relationship between obesity and PE has not yet been specifically investigated. The aim of this study was to evaluate the relationships of these two conditions. Between January 2008 and December 2009, we evaluated consecutive patients with lifelong PE in the urology outpatient clinic. Control cases without lifelong PE were selected randomly among cases attending the department of internal medicine for a checkup procedure. The age and sex of control group were matched with that of the study group. Body mass index (BMI) of each case was calculated using the World Health Organization criteria by the measurements of the physician instead of relying on verbal expressions. The mean (+/-s.d.) age of the premature ejaculators was 31.7+/-5.7 (range 21-51) years and in the control cases it was 32.3+/-6.7 (range 22-54) years. The comparison of the mean (+/-s.d.) weight between the study (74.1+/-11.2 kg) and control groups (81.9+/-6.4 kg) revealed a significant difference (Pobese cases in the control group (n=26, 24.1%) was three times greater than the obese premature ejaculators (Pobesity, and we found that patients with lifelong PE were leaner than the healthy control cases.

    Full Text Available Introduction Fetal and preterm infant brain is especially vulnerable to hemorrhagic and ischemic damage at the end of the second and at the beginning of the third trimester. This is due to vascular, cellular and anatomic characteristics of the brain during development. In premature babies, there is a physiological instability and limited autoregulation of cerebral circulation. Hemorrhagic and ischemic damages often occur together, though pathophysiological processes leading to lesions are different. Material and methods The paper deals with a detailed analysis of 860 ultrasound brain scans of prematurely born children. The examinations were performed at the Ultrasound Department of the Institute of Child and Youth Health Care in Novi Sad. 707 vaginally born premature infants and 153 premature infants born by Cesarean section were examined. The bleeding was graded according to the Papile classification. Results and Discussion Out of 384 children with diagnosed grade I hemorrhage, 75 premature infants (19.5% were born by Cesarean section. In the group of children with grade II hemorrhage, operative deliveries account for 14.7%. From the total of 85 children with grade III hemorrhage, (intraventricular bleeding with chamber dilatation, only 6 premature infants were born by Cesarean section (7%. Intra-parenchymal bleeding was diagnosed in a very small number of premature infants; 0.32% of all diagnosed hemorrhages were grade IV hemorrhages. In this group there were no children born by Cesarean section. The increase of hemorrhage grade is accompanied by a greater rate of pelvic presentation and manual assistance by Bracht. There were 240 prematurely born children with no echosonographically diagnosed hemorrhage, 38% of all examined premature infants. From this number, 13.3% of neonates were born by Cesarean section.

The main part of the essay includes an interpretation of the television series Lost — Joanna Roszak investigates philosophical references in the series and indicates biblical contexts (“Am I my brother’s keeper?”. A very apt comment to many episodes in the series is, according to the author, the formula told by Z.

It is a similar defencelessness in which the main characters of Lost try to struggle the reality, even if they live together, and die all alone. Collective memory has become a safeguard for the community in the world, which is to be destined for homelessness and forlornness. The other person though becomes a reference point — it is him or her that makes it possible to find the way home.

Im Original lautet die Aussage: "un objet concret est un objet abstrait auquel on a fini par s'habituer." Schwartz erläutert sie am Beispiel des Integrals über {e^{-1/2{x^2}}} , das den Wert Wurzel aus 2π hat und in dem sich also die Zahlen e und π verknüpfen. Was Schwartz aber vor allem ausdrücken will, ist dies: Das mathematische Verständnisd geht langsam vor sich und es bedarf der Anstrengung. "Es ist eine Frage der Zeit und der Energie", sagt Schwartz, und gerade dies mache es so schwer, die höhere Mathematik unter das Volk zu bringen. Das Lernen und Lehren von Mathematik laufe eben mühevoll und langsam ab.

    In this paper,we use symbolic transfer entropy to study the coupling strength between premature signals.Numerical experiments show that three types of signal couplings are in the same direction.Among them,normal signal coupling is the strongest,followed by that of premature ventricular contractions,and that of atrial premature beats is the weakest.The T test shows that the entropies of the three signals are distinct.Symbolic transfer entropy requires less data,can distinguish the three types of signals and has very good computational efficiency.

    Relationship marketing is in vogue. And why not? The new, increasingly efficient ways that companies have of understanding and responding to customers' needs and preferences seemingly allow them to build more meaningful connections with consumers than ever before. These connections promise to benefit the bottom line by reducing costs and increasing revenue. Unfortunately, a close look suggests that the relationships between companies and customers are troubled ones, at best. Companies may delight in learning more about their customers and in being able to provide features and services to please every possible palate. But customers delight in neither. In fact, customer satisfaction rates in the United States are at an all-time low, while complaints, boycotts, and other expressions of consumer discontent are on the rise. This mounting wave of unhappiness has yet to reach the bottom line. Sooner or later, however, corporate performance will suffer unless relationship marketing becomes what it is supposed to be--the epitome of customer orientation. Ironically, the very things that marketers are doing to build relationships with customers are often the things that are destroying those relationships. Relationship marketing is powerful in theory but troubled in practice. To prevent its premature death, marketers need to take the time to figure out how and why they are undermining their own best efforts, as well as how they can get things back on track.

    Chk1 inhibits the premature activation of the cyclin-B1-Cdk1. However, it remains controversial whether Chk1 inhibits Cdk1 in the centrosome or in the nucleus before the G2-M transition. In this study, we examined the specificity of the mouse monoclonal anti-Chk1 antibody DCS-310, with which the centrosome was stained. Conditional Chk1 knockout in mouse embryonic fibroblasts reduced nuclear but not centrosomal staining with DCS-310. In Chk1(+/myc) human colon adenocarcinoma (DLD-1) cells, Chk1 was detected in the nucleus but not in the centrosome using an anti-Myc antibody. Through the combination of protein array and RNAi technologies, we identified Ccdc-151 as a protein that crossreacted with DCS-310 on the centrosome. Mitotic entry was delayed by expression of the Chk1 mutant that localized in the nucleus, although forced immobilization of Chk1 to the centrosome had little impact on the timing of mitotic entry. These results suggest that nuclear but not centrosomal Chk1 contributes to correct timing of mitotic entry.

    Full Text Available Objectives: Rupture of membranes prior to the onset of labor is known as Premature Rupture of Membranes (PROM. Early and correct diagnosis is crucial in order to prevent fetal and maternal risks that can be life threatening. We aimed to investigate the diagnostic ability of the tests in PROM. Materials and Methods: Nitrazine test, fern test, amnio-dye test, biochemical tests (insulin-like growth factor binding protein-1 and placental alpha microglobulin-1 were evaluated in terms of effectiveness in diagnosis of PROM. Results: A gold standard method has not yet been defined in PROM. Diagnostic tests (nitrazine test, fern test, Insulin-like Growth Factor Binding Protein-1 “IGFBP-1” and Placental Alpha Microglobulin-1 “PAMG-1” should be used when the diagnosis is not certain following history, examination with sterile speculum and ultrasonography evaluation. Conclusion: IGFBP-1 and PAMG-1 are tests based on bedside immunochromatographic method. Especially, PAMG-1 comes into prominence with its high sensitivity and specificity.

    Progeria is characterized by clinical features that mimic premature ageing. Although the mutation responsible for this syndrome has been deciphered, the mechanism of its action remains elusive. Progeria research has gained momentum particularly in the last two decades because of the possibility of revealing evidences about the ageing process in normal and other pathophysiological conditions. Various experimental models, both in vivo and in vitro, have been developed in an effort to understand the cellular and molecular basis of a number of clinically heterogeneous rare genetic disorders that come under the umbrella of progeroid syndromes (PSs). As per the latest clinical trial reports, Lonafarnib, a farnesyltranferase inhibitor, is a potent 'drug of hope' for Hutchinson-Gilford progeria syndrome (HGPS) and has been successful in facilitating weight gain and improving cardiovascular and skeletal pathologies in progeroid children. This can be considered as the dawn of a new era in progeria research and thus, an apt time to review the research developments in this area highlighting the molecular aspects, experimental models, promising drugs in trial and their implications to gain a better understanding of PSs.

  1. Telomeres, telomerase and premature ovarian failure

    Full Text Available Telomeres are specialized structures at the ends of chromosomes, consisting of six repeated nucleotides in TTAGGG sequence. Genome stability is partly maintained by the architecture of telomeres and is gradually lost as telomeres progressively shorten with each cell replication. Critically shortened telomeres are recognized by DNA repair mechanisms as DNA damage and the cell replication cycle stops. The cell eventually dies or undergoes cell apoptosis. Telomere represents a cellular marker of biological age and are therefore also called cell mitotic clock. The enzyme that counteracts telomere shortening by adding nucleotides to the 3’ end of DNA strand is called telomerase. It is composed of the RNA subunit (TR, which is special type of messenger RNA (mRNA, the catalytic protein subunit (TERT, which works as a reverse transcriptase and numerous additional proteins. Telomerase is active in some germline, epithelial and haemopoietic cells, but in most somatic cells the activity is undetectable. In literature, the length of telomeres is closely connected with premature ovarian failure (POF. POF is generally defined as the onset of menopause before the age of 40. The causes of disease are genetical, autoimmune, iatrogenic or if we cannot establish the cause – idiopathic. A lot of studies examined correlation between idiopathic POF, length of telomeres and telomerase activity. The studies mostly show that women with POF have shortened telomeres and decreased activity of telomerase as compared to healthy women.

    Objective To evaluate the effect of interventions for premature ejaculation (PE) in the management of patients with chronic prostatitis and secondary premature ejaculation. Methods Totally 90 patients diagnosed as chronic prostatitis with PE were randomly divided into control group (n=45) and interventional group (n=45). Control group received a conventional therapy consisted of oral administration of antibiotics,α-receptor blocker,and proprietary Chinese medicine for clearing away heat and promoting diuresis. Interventional group received a conventional therapy combined with treatment for ameliorating the PE symptom (oral dapoxetine on-demand and ejaculation control exercise).National Institutes of Health Chronic Prostatitis Symptom Index (NIH-CPSI),Chinese Index of Sexual Function for Premature Ejaculation (CIPE)-5 questionnaires,intravaginal ejaculatory latency time,and the number of coituses per week were applied for evaluating the treatment outcomes. Results Follow-up was accomplished in 35 and 38 patients in the control and interventional group.The CIPE-5 score,intravaginal ejaculatory latency time,and the number of coituses per week were significantly improved in both two groups but more significantly in interventional group (all P<0.05). The NIH-CPSI pain,urination,and quality of life subscores and total score were improved significantly in both two groups after treatment,but the NIH-CPSI pain and quality of life subscores had been improved more significantly in the interventional group (all P<0.05). The variation of NIH-CPSI was negatively correlated with that of CIPE-5 in both two groups (r=-0.362,P=0.016;r=-0.330,P=0.021). Conclusions For CP with secondary PE patients,the interventions for PE can not only improve the quality of sexual life but also help improve the NIH-CPSI pain and quality of life subscores. PE should be routinely screened and treated during the management of CP.p.

    Length and thickness of 152 corpus callosa were measured in neonates within 24 hours of birth. Using ultrasonic diagnostic equipment with a neonatal brain-specific probe, corpus callosum length and thickness of the genu, body, and splenium were measured on the standard mid-sagittal plane, and the anteroposterior diameter of the genu was measured in the coronal plane. Results showed that corpus callosum length as well as thickness of the genu and splenium increased with tional age and birth weight, while other measures did not. These three factors on the standard mid-sagittal plane are therefore likely to be suitable for real-time evaluation of corpus callosum velopment in premature infants using cranial ultrasound. Further analysis revealed that thickness of the body and splenium and the anteroposterior diameter of the genu were greater in male infants than in female infants, suggesting that there are sex differences in corpus callosum size during the neonatal period. A second set of measurements were taken from 40 premature infants whose gestational age was 34 weeks or less. Corpus callosum measurements were corrected to a gestational age of 40 weeks, and infants were grouped for analysis depending on the outcome of a neonatal behavioral neurological assessment. Compared with infants with a normal neurological assessment, corpus callosum length and genu and splenium thicknesses were less in those with abnormalities, indicating that corpus callosum growth in premature infants is associated with neurobehavioral development during the early extrauterine stage.

  5. Ist hohe Salzzufuhr während der Schwangerschaft verantwortlich für eine veränderte Nierenmorphologie beim Fetus?

    2009-01-01

    Full Text Available Während einer normalen Schwangerschaft steigen Plasmavolumen, Plasma-Renin- Aktivität (PRA, Plasma-Angiotensin-II- und Aldosteron-Spiegel an. Paradoxerweise sinkt der arterielle Blutdruck deutlich ab. Die Präeklampsie ist gekennzeichnet durch mütterliche Hypertonie, Proteinurie, Verminderung des Blutvolumens sowie veränderte Aktivität des RAAS. Das Auftreten einer Präeklampsie wird in experimentellen Studien durch hohe Salzzufuhr gesteigert. Hohe Salzzufuhr stimuliert die Freisetzung kardiotonischer Steroide, welche im Tierexperiment zur Entwicklung der Präeklampsie beitragen. Antikörper, welche die kardiotonischen Steroide neutralisieren, führen zur Senkung des arteriellen Blutdrucks bei Schwangeren mit Präeklampsie ebenso wie bei experimenteller Präeklampsie. Niedriges Geburtsgewicht ist assoziiert mit niedriger Nephronenzahl und Hypertonie im Erwachsenenalter. Experimentelle Studien zeigten, dass hohe Salzzufuhr in der Schwangerschaft unabhängig vom Geburtsgewicht zu erniedrigter Nephronenzahl und späterem Auftreten einer Hypertonie führt. Ob fetale Programmierung durch verminderte plazentare Durchblutung infolge von Vasokonstriktion durch hohe Spiegel kardiotonischer Steroide oder nach transplazentarem Übertritt durch direkte Effekte kardiotonischer Steroide auf fetale Organogenese vermittelt wird, ist gegenwärtig noch unklar.

    Hypothalamic-pituitary-gonadotropic activity was investigated in 9 girls with premature thelarche, and compared with that in 9 healthy girls and 6 girls with true precocious puberty. The gonadotropin stimulation test with luteinising hormone-releasing hormone was used. Girls with premature thelarche showed luteinising hormone response resembling that of normal girls, and follicle-stimulating hormone (FSH) response quite similar to that of girls with precocious puberty. This suggests that in premature thelarche there is a partial activation of the diencephalic-hypophyseal-gonadal axis, which affects FSH only. Premature thelarche therefore, should be considered as one of the disorders due to altered sensitivity of the hypothalamic receptors which regulate sex maturation. PMID:6779715

    Medical technology has made significant advances over the last few decades with smaller and more dynamic pacemakers. However, technical failures leading to premature replacement is a cause of concern. We present a series of Medtronic EnRhythm devices that reached premature elective replacement indicator (ERI). The database of Centre of Heart Rhythm Disorders was searched for EnRhythm device implantation from 2006 to 2011. Battery depletion <8.5 years was considered premature considering the projected average longevity to be 8.5-10.5 years. An unexpected premature ERI was defined when it was reached within 3 months of last normal check. Device follow-up was conducted every 3 months after advisory. A total of 88 EnRhythm pacemakers were implanted. Over a median follow-up of 6.2 years (range: 0.3-9.2), 39 (44.3%) EnRhythm devices reached premature ERI. In 11 (28%), ERI was not recognized and patients were being investigated for other causes of unsteadiness or dyspnea prior to device check. Notably, three (7%) patients had premature ERI < 3.5 years. Ten (25.6%) had sudden and unexpected premature ERI. While asynchronous pacing was observed, there were no cases of absence of pacing. The rate of premature ERI for EnRhythm devices was 44.3%, significantly higher than reported by the manufacturer. Of concern, a sizeable proportion occurred unexpectedly, warranting more frequent reviews and empirical replacement in some patients. With the experience of the EnRhythm, appropriate monitoring strategies are recommended for future advisories. © 2017 Wiley Periodicals, Inc.

  1. Premature aging in telomerase-deficient zebrafish

    2013-09-01

    The study of telomere biology is crucial to the understanding of aging and cancer. In the pursuit of greater knowledge in the field of human telomere biology, the mouse has been used extensively as a model. However, there are fundamental differences between mouse and human cells. Therefore, additional models are required. In light of this, we have characterized telomerase-deficient zebrafish (Danio rerio as the second vertebrate model for human telomerase-driven diseases. We found that telomerase-deficient zebrafish show p53-dependent premature aging and reduced lifespan in the first generation, as occurs in humans but not in mice, probably reflecting the similar telomere length in fish and humans. Among these aging symptoms, spinal curvature, liver and retina degeneration, and infertility were the most remarkable. Although the second-generation embryos died in early developmental stages, restoration of telomerase activity rescued telomere length and survival, indicating that telomerase dosage is crucial. Importantly, this model also reproduces the disease anticipation observed in humans with dyskeratosis congenita (DC. Thus, telomerase haploinsufficiency leads to anticipation phenomenon in longevity, which is related to telomere shortening and, specifically, with the proportion of short telomeres. Furthermore, p53 was induced by telomere attrition, leading to growth arrest and apoptosis. Importantly, genetic inhibition of p53 rescued the adverse effects of telomere loss, indicating that the molecular mechanisms induced by telomere shortening are conserved from fish to mammals. The partial rescue of telomere length and longevity by restoration of telomerase activity, together with the feasibility of the zebrafish for high-throughput chemical screening, both point to the usefulness of this model for the discovery of new drugs able to reactivate telomerase in individuals with DC.

  2. Emerging and investigational drugs for premature ejaculation.

    McMahon, Chris G

    2016-08-01

    Over the past 20-30 years, the premature ejaculation (PE) treatment paradigm, previously limited to behavioural psychotherapy, has expanded to include drug treatment. Pharmacotherapy for PE predominantly targets the multiple neurotransmitters and receptors involved in the control of ejaculation which include serotonin, dopamine, oxytocin, norepinephrine, gamma amino-butyric acid (GABA) and nitric oxide (NO). The objective of this article is to review emerging PE interventions contemporary data on the treatment of PE was reviewed and critiqued using the principles of evidence-based medicine. Multiple well-controlled evidence-based studies have demonstrated the efficacy and safety of selective serotonin reuptake inhibitors (SSRIs) in delaying ejaculation, confirming their role as first-line agents for the medical treatment of lifelong and acquired PE. Daily dosing of SSRIs is likely to be associated with superior fold increases in IELT compared to on-demand SSRIs. On-demand SSRIs are less effective but may fulfill the treatment goals of many patients. Integrated pharmacotherapy and CBT may achieve superior treatment outcomes in some patients. PDE-5 inhibitors alone or in combination with SSRIs should be limited to men with acquired PE secondary to co-morbid ED. New on-demand rapid acting SSRIs, oxytocin receptor antagonists, or single agents that target multiple receptors may form the foundation of more effective future on-demand medication. Current evidence confirms the efficacy and safety of dapoxetine, off-label SSRI drugs, tramadol and topical anaesthetics drugs. Treatment with α1-adrenoceptor antagonists cannot be recommended until the results of large well-designed RCTs are published in major international peer-reviewed medical journals. As our understanding of the neurochemical control of ejaculation improves, new therapeutic targets and candidate molecules will be identified which may increase our pharmacotherapeutic armamentarium.

    Abstract Background: Premature ejaculation (PE) is the most prevalent male sexual dysfunction. Epidemiologic findings are inconsistent concerning the risk for depression associated with PE. Objective: The aim of this study was to investigate the potential association between between depression and risk of PE. Data sources: We conducted a literature search of PubMed, Embase, and the Cochrane Library from these databases’ inception through June 2014 for observational epidemiological studies examining the association between depression on risk of PE. Study eligibility criteria: Studies were selected if they reported the risk estimates for PE associated with depression. Participants: patients>18 years of age suffering from PE. Interventions: a history of depressive disorder. Study appraisal and synthesis methods: These odds ratios (ORs) were pooled using a random or fixed effects model and were tested for heterogeneity. Subgroup analysis was employed to explore heterogeneity. Results: Eight trials involving 18,035 patients were included in the meta-analysis. Depression were statistically significantly associated with the risk of PE (OR = 1.63, 95% CI:1.42–1.87). There was no evidence of between-study heterogeneity (P = 0.623, I2 = 0.0%). The association was similar when stratified by mean age, geographical area, study design, sample size, publication year, and controlling key confounders. Limitations: The severity of depression and PE could not be identified due to unavailable data of trials. No evidence of publication bias was observed. Conclusions: These findings provide evidence that depression is associated with a significantly increased risk of PE. In addition, more prospective studies are necessary to evaluate the association and identify the ideal treatment. Systematic review registration number: CRD42016041272 PMID:27583879

    Background Based on our clinical experience, the number of dorsal penile nerves in patients with primary premature ejaculation (PPE) is not consistent with the average number (2 branches). In this study, we evaluated the number and distribution of dorsal penile nerves among healthy Chinese adults and patients with PPE.Methods The dorsal nerve of the penis, the deep dorsal vein of the penis, and the dorsal artery of the penis between the deep fascia of the penis and the albuginea penis were carefully educed, observed, and counted in 38 adult autopsy specimens. The number and distribution of the dorsal penile nerve in 128 surgical patients with PPE were determined. Results The numbers of dorsal penile nerves of the 38 cases were as follows:7 branches in 1 case; 6 branches in 1 case; 5 branches in 6 cases; 4 branches in 9 cases; 3 branches in 14 cases; and 2 branches in 7 cases. Most of the dorsal nerves were parallel to each other and in the dorsum of the penis. In only 8 cases, the branches were connected by some communicating branches. In 4 cases, 1 or 2 thin dorsal nerves continued their pathway over the ventral aspect of the penis. The average number of branches of the dorsal penile nerve in patients with PPE was 7.16. Conclusions Based on the study of 38 cases, the average number of dorsal penile nerves was 3.55 branches and that of patients with PPE was greater. These preliminary results suggest that the excessive dorsal penile nerves may have an impact on PPE via increased sensitivity and provide topographic data for the possible treatment of PPE.

    Aim: To assess the psychometric properties of the Chinese Index of Premature Ejaculation (CIPE).Methods: The sexual function of 167 patients with and 114 normal controls without premature ejaculation (PE) were evaluated with CIPE. All subjects were married and had regular sexual activity. The CIPE has 10 questions, focusing on libido, erectile function, ejaculatory latency, sexual satisfaction and difficulty in delaying ejaculation, self-confidence and depression. Each question was responded to on a 5 point Likert-type scale. The individual question score and the total scale score were analyzed between the two groups. Results: There were no significant differences between the age, duration of marriage and educational level (P>0.05) of patients with and without PE and normal controls. The mean latency of patients with PE and normal controls were 1.6±1.2 and 10.2±9.5 minutes,respectively. Significant differences between patients with (26.7±4.6) PE and normal controls (41.9±4.0) were observed on the total score of CIPE (P15 point) 19.8%, moderate (10~14 point) 62.8% and severe (<9point) 16.7%. Conclusion:The CIPE-5 is a useful method for the evaluation of sexual function of patients with PE and can be used as a clinical endpoint for clinical trials studying the efficacy of pharmacological intervention.

    Premature birth is associated with poor metabolic health in both sexes, potentially via earlier pubertal timing. We examined the associations of gestational age and premature birth (Premature girls reached puberty about 4 months later than girls with ≥ 41 weeks' gestation (time ratio = 1.04 [95% confidence interval = 1.01-1.06]), adjusted for mother' age of menarche, mother's place of birth, and smoking during pregnancy. Gestational age was not associated with onset of puberty in boys (test for interaction by sex, P Premature birth was not related to earlier onset of puberty; instead, premature girls had later onset of puberty. Thus, the association between premature birth and subsequent cardiovascular risk is probably not mediated through the timing of pubertal onset. It is unclear whether onset, duration, or tempo of puberty is more relevant to the detrimental consequences of early puberty. Further studies investigating intrauterine, infant, and childhood influences on the duration and tempo of puberty may help unravel the early origins of cardiovascular diseases.

    Children born extremely prematurely are at risk for a variety of problems with motion analysis, including problems with motion-defined (MD) form recognition [Downie, A. L. S., Jakobson, L. S., Frisk, V., & Ushycky, I. (2003). Periventricular brain injury, visual motion processing, and reading and spelling abilities in children who were extremely-low-birthweight. Journal of the International Neuropsychological Society, 9, 440-449]. The aims of the present study were (1) to examine the impact of retinopathy of prematurity (ROP) and mild periventricular brain injury (PVBI) on MD form processing in this population; (2) to assess relationships between MD form recognition in these children and their performance in several other areas of visual competence. To this end, a battery of visual and visuomotor tests was administered to 43, 5- and 6-year old, extremely premature children, all of whom had escaped severe PVBI. A group of full-term controls was also studied. Relative to controls, premature children displayed clear deficits in MD form recognition and these deficits were related to the presence of ROP and/or mild PVBI, rather than to a history of prematurity per se. Regression analyses revealed significant associations in premature children between MD form processing deficits and problems with visual search, stereopsis, visuoconstructive and graphomotor skills, motor development, and Performance IQ. The results suggest that assessment of sensitivity to MD forms may be useful in the early identification of preterm children at greatest risk for visual problems associated with dorsal stream dysfunction.

    This study examined the neural correlates of intentional and automatic number processing (indexed by number comparison and physical Stroop task, respectively) in 6- and 7-year-old children born prematurely. Behavioral results revealed significant numerical distance and size congruity effects. Imaging results disclosed (1) largely overlapping fronto-parietal activation for intentional and automatic number processing, (2) a frontal to parietal shift of activation upon considering the risk factors gestational age and birth weight, and (3) a task-specific link between math proficiency and functional magnetic resonance imaging (fMRI) signal within distinct regions of the parietal lobes-indicating commonalities but also specificities of intentional and automatic number processing.

    Early repolarization pattern (ERP) is a common ECG variant, characterized by J point elevation manifested either as terminal QRS slurring (the transition from the QRS segment to the ST segment) or notching (a positive deflection inscribed on terminal QRS complex) associated with concave upward ST-segment elevation and prominent T waves in at least two contiguous leads. Aim of this observational study was to compare number of premature ventricular beats in the different groups of patients with early repolarization. The result of this observational study shows that there are: 1,74 fold higher number of premature ventricular beats in 41-74 year subgroup VS 19-40 year subgroup; 1,31 fold higher number of premature ventricular beats in male subgroup VS female subgroup (But this difference is not statistically significant, because t=1,49, p=0,141); 2,85 fold higher number of premature ventricular beats in CAD+ERP subgroup VS ERP without CAD subgroup; 1,74 fold higher number of premature ventricular beats in HF+ERP subgroup VS ERP without HF subgroup; 1,81 fold higher number of premature ventricular beats in CAD+ERP subgroup VS CAD without ERP subgroup; 1,58 fold higher number of premature ventricular beats in HF+ERP subgroup VS HF without ERP subgroup; So, CAD+ERP is very arrhythmogenic condition, after this is HF+ERP, Then Age. This study shows that ERP independently increase number of PVB in different groups (CAD, HF). This is principally new and very important result. Also the number of patients is enough to make this conclusion.

    The Early Treatment for Retinopathy of Prematurity trial demonstrated that peripheral retinal ablation of eyes with high-risk prethreshold retinopathy of prematurity (early treatment) is associated with improved visual outcomes at 9 months' corrected gestational age compared with treatment at threshold disease (conventional management). However, early treatment increased the frequency of laser therapy, anesthesia with intubation, treatment-related systemic complications, and the need for repeat treatments. To determine the cost-effectiveness of an early treatment strategy for retinopathy of prematurity compared with conventional management. We developed a stochastic decision analytic model to assess the incremental cost of early treatment per eye with severe visual impairment prevented. We derived resource-use and efficacy estimates from the Early Treatment for Retinopathy of Prematurity trial's published outcome data. We used a third-party payer perspective. Our primary analysis focused on outcomes from birth through 9 months' corrected gestational age. A secondary analysis used a lifetime horizon. Parameter uncertainty was quantified by using probabilistic and deterministic sensitivity analyses. The incremental cost-effectiveness of early treatment was $14,200 per eye with severe visual impairment prevented. There was a 90% probability that the cost-effectiveness of early treatment would be less than $40,000 per eye with severe visual impairment prevented and a 0.5% probability that early treatment would be cost-saving (less costly and more effective). Limiting early treatment to more severely affected eyes (eyes with "type 1 retinopathy of prematurity" as defined by the Early Treatment for Retinopathy of Prematurity trial) had a cost-effectiveness of $6,200 per eye with severe visual impairment prevented. Analyses that considered long-term costs and outcomes found that early treatment was cost-saving. Early treatment of retinopathy of prematurity is both

    Full Text Available Introduction. More and more survival of newborns with small or extremely small body mass at birth, as well as increasing percent of prematurely born babies, have emphasized the significance of intracranial haemorrhage problem. Prematurely born infants are under increased risk for strabismus, amblyopia, blinding and hearing loss. Objective. Establishing the frequency of sensory damages (damage of sight and hearing in prematurely born infants with various degrees of intracranial haemorrhage. Methods. The study is prospective, controlled and included 120 prematurely born infants with diagnosed four different grade intracranial haemorrhage on ultrasonic examination of the central nervous system. The study excluded prematurely born children from twin pregnancies with congenital malformations and stoppage of intrauterine growth. Ophthalmological examination was done at 9, 12, and 36 months of postnatal age. Audilogical examination was done after delivery, at 2 months of age. Results. There are statistically significant differences (p<0.01 related to the presence of strabismus among groups of examinees with vairious hemorrhage degrees. Strabismus was present only in one premature infant with 1st and in 10 children (33.3% with the 4th degree. Amblyopia occurred only among examinees with 4th degree hemorrhage. There were statistically significant differences (p<0.01 related to the finding of transitory otoacoustic emission of the left ear and the right ear among the groups. The finding of the right ear was not usual in 7 examinees from the 4th degree hemorrhage. The finding of the left ear was not usual in 1 examinee from the third and in 7 examinees from the fourth group. Conclusion. Prematurely born children with a higher degree intracranial hemorrhage have a greater risk for the loss of hearing and development of visual handicap.

    Full Text Available Abstract Background Studies have consistently found a high incidence of neonatal medical problems, premature births and low birth weights in abused and neglected children. One of the explanations proposed for the relation between neonatal problems and adverse parenting is a possible delay or disturbance in the bonding process between the parent and infant. This hypothesis suggests that due to neonatal problems, the development of an affectionate bond between the parent and the infant is impeded. The disruption of an optimal parent-infant bond -on its turn- may predispose to distorted parent-infant interactions and thus facilitate abusive or neglectful behaviours. Video Interaction Guidance (VIG is expected to promote the bond between parents and newborns and is expected to diminish non-optimal parenting behaviour. Methods/design This study is a multi-center randomised controlled trial to evaluate the effectiveness of Video Interaction Guidance in parents of premature infants. In this study 210 newborn infants with their parents will be included: n = 70 healthy term infants (>37 weeks GA, n = 70 moderate term infants (32–37 weeks GA which are recruited from maternity wards of 6 general hospitals and n = 70 extremely preterm infants or very low birth weight infants (i.e. full term infants and their parents, receiving care as usual, a control group (i.e. premature infants and their parents, receiving care as usual and an intervention group (i.e. premature infants and their parents, receiving VIG. The data will be collected during the first six months after birth using observations of parent-infant interactions, questionnaires and semi-structured interviews. Primary outcomes are the quality of parental bonding and parent-infant interactive behaviour. Parental secondary outcomes are (posttraumatic stress symptoms, depression, anxiety and feelings of anger and hostility. Infant secondary outcomes are behavioral aspects such as crying

    Early repolarization pattern (ERP) is a common ECG variant, characterized by J point elevation manifested either as terminal QRS slurring (the transition from the QRS segment to the ST segment) or notching (a positive deflection inscribed on terminal QRS complex) associated with concave upward ST-segment elevation and prominent T waves in at least two contiguous leads. 36 patients were included in this observation. There are 36 patients (19-68 years old) with early repolarization ECG patterns. All this 36 patients were divided into two groups according to their level of J point elevation. First group consisted of 12 patients with J point elevation ≥0,15 mV; second group - of 24 patients with J point elevation premature ventricular beat during 24 h. Before and during this monitoring patients don't take any antyarrhythmic drugs. In the first group (J point elevation ≥0,15 mV) sum of premature ventricular beats were 27432, in the second group (J point elevation premature ventricular beats were 31 896. The results of this observational study shows that there is 1,72 fold higher number of premature ventricular beats in first group. So, J point elevation equal or more then 0,15 mV, is more arrhythmogenic and induces premature ventricular beats. This is principally new and very important result.

    To identify the meanings attributed by mothers to hypertensive disorders of pregnancy (HDPs) and their consequences, such as premature birth and hospitalization of the infant in the neonatal intensive care unit (NICU). A qualitative study, based on the Central Nucleus Theory, with 70 women who had hypertensive disorders of pregnancy and preterm delivery. We used the technique of free word association (FWAT) with three stimuli: high blood pressure during pregnancy, prematurity and NICU. We obtained 1007 evocations, distributed as follows: high blood pressure during pregnancy (335) prematurity (333) and NICU (339). These constituted three thematic units: representation of HDPs, prematurity and the NICU. The categories death and negative aspects were inherent to the three units analyzed, followed by coping strategies and needs for care present in HDPs and prematurity. The study had death as its central nucleus, and highlighted the subjective aspects present in the high risk pregnancy and postpartum cycle. It is hoped that this research will contribute to qualifying nursing care for women confronting the problem of HDPs, so that they can cope with less impacts from the adverse effects of high risk pregnancy and birth.

    Full Text Available BackgroundIn the extremities of premature infants, the skin and subcutaneous tissue are very pliable due to immaturity and have a greater degree of skin laxity and mobility. Thus, we can expect wounds to heal rapidly by wound contraction. This study investigates wound healing of full-thickness defects in premature infant extremities.MethodsThe study consisted of 13 premature infants who had a total of 14 cases of full-thickness skin defects of the extremities due to extravasation after total parenteral nutrition. The wound was managed with intensive moist dressings with antibiotic and anti-inflammatory agents. After wound closure, moisturization and mild compression were performed.ResultsMost of the full-thickness defects in the premature infants were closed by wound contraction without granulation tissue formation on the wound bed. The defects resulted in 3 pinpoint scars, 9 linear scars, and 2 round hypertrophic scars. The wounds with less granulation tissue were healed by contraction and resulted in linear scars parallel to the relaxed skin tension line. The wounds with more granulation tissue resulted in round scars. There was mild contracture without functional abnormality in 3 cases with a defect over two thirds of the longitudinal length of the dorsum of the hand or foot. The patients' parents were satisfied with the outcomes in 12 of 14 cases.ConclusionsFull-thickness skin defects in premature infants typically heal by wound contraction with minimal granulation tissue and scar formation probably due to excellent skin mobility.

    Full Text Available Introduction:  Premature neonates admitted in NICU besides being separated from their mothers are prone to inevitably painful and stressful situations. Kangaroo care is the most effective method to get rid of this separation and its negative consequences. This study was performed to determine the experiences of mothers having premature neonates concerning Kangaroo care.   Material and Methods: The present study is a qualitative research in which focus group discussion method is used for data collection. Research society consisted of mothers having premature neonates Research group reread and categorized the qualitative findings. Contents of interviews were analyzed using the conventional interpretation approach introduced by Dicklman Method.   Results: Through content analysis of information emerged two major categories including mothers’ experiences about advantages of kangaroo care in interaction with neonate, and, feeling of physical-mental healthiness of neonate. Executive obstacles of kangaroo care from mothers’ standpoint were also discussed, which will be subsequently presented.   Discussion: According to the obtained results, it seems vital to highlight kangaroo care as a safe and effective clinical care-taking treatment in nursery of premature neonates in all hospitals. Nurses shall provide all mothers with the needed instructions for holding the premature and lower-weight neonate properly on their chests and shall promote their knowledge level concerning positive effects of kangaroo care including induction of tranquil sleep, optimization of physiological conditions of neonate, and removal of suckling obstacles.

    Calpain 7, a mammalian ortholog of yeast Cpl1/Rim13 and fungal PalB, is an atypical calpain that lacks a penta-EF-hand domain. Previously, we reported that a region containing a tandem repeat of microtubule-interacting and transport (MIT) domains in calpain 7 interacts with a subset of endosomal sorting complex required for transport (ESCRT)-III-related proteins, suggesting involvement of calpain 7 in the ESCRT system. Although yeast and fungal calpains are thought to be involved in alkaline adaptation via limited proteolysis of specific transcription factors, proteolytic activity of calpain 7 has not been demonstrated yet. In this study, we investigated the interaction between calpain 7 and a newly reported ESCRT-III family member, increased sodium tolerance-1 (IST1), which possesses two different types of MIT-interacting motifs (MIM1 and MIM2). We found that glutathione-S-transferase (GST)-fused tandem MIT domains of calpain 7 (calpain 7MIT) pulled down FLAG-tagged IST1 expressed in HEK293T cells. Coimmunoprecipitation assays with various deletion or point mutants of epitope-tagged calpain 7 and IST1 revealed that both repetitive MIT domains and MIMs are required for efficient interaction. Direct MIT-MIM binding was confirmed by a pulldown experiment with GST-fused IST1 MIM and purified recombinant calpain 7MIT. Furthermore, we found that the GST-MIM protein enhances the autolysis of purified Strep-tagged monomeric green fluorescent protein (mGFP)-fused calpain 7 (mGFP-calpain 7-Strep). The autolysis was almost completely abolished by 10 mmN-ethylmaleimide but only partially inhibited by 1 mm leupeptin or E-64. The putative catalytic Cys290-substituted mutant (mGFP-calpain 7(C290S)-Strep) showed no autolytic activity. These results demonstrate for the first time that human calpain 7 is proteolytically active, and imply that calpain 7 is activated in the ESCRT system. © 2010 The Authors Journal compilation © 2010 FEBS.

  11. [Preterm premature rupture of membranes: active or expectant management?].

    Science.gov (United States)

    Kayem, G; Maillard, F

    2009-04-01

    Preterm premature rupture of membranes (PPROM) occurs in 3% of pregnancies and is responsible for 30% of preterm births. The management is discussed between active and expectant management. French recommendations let open both possibilities. The risks described in the case of PPROM are those of prematurity, maternofetal infection, acute procidence of the umbilical cord and abruptio placentae. Before 32 weeks of gestation (WG) and even 34 WG, a prolongation of one week of gestational age significantly decreases neonatal mortality and morbidity. Therefore, most of the authors choose expectant management in case of PPROM. Between 34 and 37 WG, the risk of rare severe morbidity associated with prematurity has to be balanced with risks of an acute maternofetal infection and of abruptio placentae. Further randomized trials are required to choose a type of management with a sufficient level of evidence.

    Premature ventricular complex are common findings in the exam of many athletes. There is no extensive scientific evidence in the management of this situation particularly when associated with borderline contractile function of the left ventricle. In this case report, we present a 35-year-old asymptomatic healthy athlete with high incidence (over 10,000 beats in 24 h) of premature ventricular complex and left ventricular dilatation with dysfunction, which persisted after a resting period of 6 months without training. We performed radiofrequency ablation of the premature ventricular complex focus. After 1-year follow-up, he was asymptomatic without arrhythmia and the left ventricle normalized its size and function as shown by echocardiogram and cardiac magnetic resonance.

    Full Text Available The article examines the modern data on the importance of breast milk in nursing premature babies. It is shown that the amount of breast milk in women, who gave birth prematurely, decreases rapidly, especially when it is impossible to get a baby latched on to the breast. There is a negative correlation between gestational age and duration of lactation. According to the opinion of both doctors and the majority of mothers, pumping out breast milk and using it in feeding a premature baby is an important psychological and physiological factor linking a mother and a child at the intensive care unit. Individual breast milk banks are a new safe and effective method for long-term keeping of breast milk.

    Full Text Available Intraventricular hemorrhage (IVH is an important cause of brain injury in premature neonates. Current study tries to define associated risk factors of IVH in preterm neonates in Aliasghar Children Hospital during 2008 to 2011. In this study, the risk factors have been evaluated in premature neonates with IVH, who had at least one brain sonography since their admission in NICU. A total of 63 premature neonates with IVH were assessed. Mean gestational age was 29.81 (24-34 weeks and mean birth weight was 1290.83±382.96 gr. Other risk factors such as sex, mode of delivery, history of using infertility drugs, maternal disease, maternal hypertension and preeclampsia, lumbar puncture, ventilator therapy and pneumothorax were considered. Because no absolute treatment for IVH is available, identifying risk factors is important in prevention and management of IVH.

    Although the premature loss of primary teeth in conjunction with early eruption may be of no clinical significance, the loss of primary or permanent teeth in the absence of trauma should not be overlooked by the clinician. Premature loss of teeth associated with systemic disease usually results from some change in the immune system or connective tissue. This chapter presented some conditions associated with loosening and/or premature loss of teeth that may be encountered in children and adolescents. The most common of these conditions appear to be hypophosphatasia and early-onset periodontitis. Other less common conditions were described to aid in forming a differential diagnosis. Other diseases that may manifest with severe oral infection, such as Wiskott-Aldrich syndrome, diabetes mellitus, or herpes zoster, could result in early tooth loss.

    2007-01-01

    This article explores the home health nurse's role in preventing respiratory syncytial virus (RSV) among premature infants. Thousands of children infected with RSV require hospitalization each year. Consistent contact with the infant alerts the nurse to subtle signs and symptoms of RSV infection, which may include nasal congestion, cough, low-grade fever, and malaise. By developing patient and caregiver trust, the home health nurse can implement an RSV prevention plan, leading to a decrease in hospitalization episodes of premature infants with RSV. Identification of patient risk factors contributing to RSV together with caregiver education is addressed in this article.

    Science.gov (United States)

    Husebye, Eystein S; Løvås, Kristian

    2009-06-01

    Autoimmune Addison's disease and autoimmune ovarian insufficiency are caused by selective targeting by T and B lymphocytes to the steroidogenic apparatus in these organs. Autoantibodies toward 21-hydroxylase are a clinically useful marker for autoimmune Addison's disease. Autoantibodies to 21-hydroxylase are found in premature ovarian insufficiency, but others also can be present, notably antibodies against side-chain cleavage enzyme. The autoimmune response primarily targets the theca cells, yielding elevated concentrations of inhibin, which is emerging as a useful diagnostic marker for autoimmune etiology of ovarian insufficiency. Little is known about its immunogenetics, but in contrast to Addison's disease, several experimental models of autoimmune premature ovarian insufficiency are available for study.

    Autism spectrum disorder (ASD) is common, life-long in nature, and can be very debilitating. Thus, an intensive search is on to identify the potential risk factors for the disorder. Premature birth has been identified as one potential factor that could influence potential symptoms of ASD. The sample for this study consisted of 1655 at risk children for developmental delays who were 17-37 months of age. Participants were divided into those diagnosed with ASD (n = 916) and children with atypical development only (n = 739). Premature births were almost twice as common for the atypical development group versus the ASD group. Implications of these data are discussed.

    2006-01-01

    Full Text Available Prematurity is the cause of 85% of neonatal morbidity and mortality. Premature rupture of the membranes (PROM is associated with 30-40% of preterm deliveries. A case-control study conducted between July 2002 and 2003 examined the correlates and risk factors for PROM in Mysore, India. WBCs in vaginal fluid, leucocytes in urine, UTI and infection with E . coli , S . aureus , C. albicans and BV were significantly associated with PROM. BV, E. coli and WBCs in vaginal fluid were independent risk factors. Screening and treatment of BV and E. coli infection in pregnancy may reduce the risk of PROM.

    Objective To explore the etiology, incidence and methods to prevent and treat severe retinopathy of prematurity (ROP),which is rapidly becoming a threat to the vision of babies in areas of the world where increasing numbers of premature babies are surviving.Data sources The data used in this review were mainly from Medline and PubMed published in English. The search term was "retinopathy of prematurity and premature birth".Study selection We discuss the historical perspectives, prevalence and incidence, classification and treatment methods of ROP in premature babies.Results Peripheral retinal ablation for eyes with severe ROP can help prevent progression to blindness and several large clinical trials have shown the effectiveness of this treatment in high risk eyes. As a greater proportion of VLBW and ELBW babies survive, the population of babies at risk increases. In various regions of the world, different identification criteria are used to determine which babies are at risk of blindness in order to provide timely diagnostic examinations and treatment as needed. Methods for preventiing ROP include better ante-natal and obstetric care leading to a reduction in the rate of prematurity, the use of ante-natal corticosteroids, and better neonatal care practices. Recent developments have indicated that management of oxygen supplementation is important for the prevention of severe ROP; however,there is not yet known what oxygen saturation target should be adopted. Sepsis increases severe ROP in very preterm infants. Genetic associations and a telemedicine approach may be explored to detect ROP. Treatment of anti-VEGF therapy are potentially useful in eyes with severe ROP, but long term effects are not yet known and such treatment should be used with great caution.Conclusions ROP is a potentially binding disease for premature babies which is becoming more prevalent with the development improving neonatal services in many countries in recent years.

    Full Text Available Abstract Background Increased survival of extremely low birth infants due to advances in antenatal and neonatal care has resulted in a population of infants at high risk of developing retinopathy of prematurity (ROP. Therapeutic interventions include the use of antenatal and postnatal steroids however, their effects on the severity of ROP is in dispute. In addition, it has not been investigated whether severe ROP is due to therapeutic interventions or due to the severity of illness. The aim of the present study was to assess the association between the incidence of severe retinopathy of prematurity (greater than stage 2 – International classification of ROP and mechanical ventilation, oxygen therapy, gestational age, antenatal and postnatal steroids in extremely low birth weight infants. Methods Neonates admitted to the neonatal intensive care unit in Lansing, Michigan, during 1993–2000 were followed to determine factors influencing the development of severe retinopathy of prematurity. Ophthalmologic examinations were started at 6 weeks and followed until resolution. We used logistic regression to estimate the relative risk (odds ratio associated with risk factors of ROP. Results Of the neonates with ≤ 1500 g birth weight, admitted to the neonatal intensive care unit, 85% (616/725 survived. Severe retinopathy of prematurity was detected in 7.8% of 576 neonates who had eye examinations. Neonates of lower gestational age (≤ 25 weeks and 26–28 weeks had an increased odds ratio of 8.49 and 3.19 for the development of severe retinopathy of prematurity, respectively, compared to those 29 weeks and older. Late postnatal steroid treatment starting after 3 weeks of life showed 2.9-fold increased odds ratio, in particular administration for two weeks and more (OR: 4.09, 95% CI: 1.52–11.03. With increasing antenatal steroids courses the risk of severe retinopathy of prematurity decreased, however, it was not significant. Lower gestational age

    Full Text Available The aim of this study was to estimate the incidence of retinopathy of permaturity (ROP and to evaluate possible neonatal risk factors for ROP. The main study was a cross-sectional study including 150 high-risk neonates born at teaching hospitals of Tehran universities referring to to Farabi Eye Hospital. The chossing critertia were birth weight less than 2500 g or gestational age younger than 37 weeks. ROP was present in 9(6% newborns, all of whom aged less than 32 weeks a birth. There was also strong association between ROP and birth weight, oxygen administration, respiratory distress syndrome and intraventricular hemorrhage. There also seems to be a higher risk for developing ROP in female neoates, those who were born by multiple gestaional pregnancies or were treated by phototherapy or transfusion and those who had suffered from bronchopulmonary dysplasia or seiss.Prematurity per se remains the strongest risk factof for ROP. Suitable criteria for screening of ROP seems to be gestational age younger than 32 weeks or birth weight less than 1500 g

    Length and thickness of 152 corpus cal osa were measured in neonates within 24 hours of birth. Using ultrasonic diagnostic equipment with a neonatal brain-specific probe, corpus cal osum length and thickness of the genu, body, and splenium were measured on the standard mid-sagittal plane, and the anteroposterior diameter of the genu was measured in the coronal plane. Results showed that corpus cal osum length as wel as thickness of the genu and splenium increased with gesta-tional age and birth weight, while other measures did not. These three factors on the standard mid-sagittal plane are therefore likely to be suitable for real-time evaluation of corpus cal osum de-velopment in premature infants using cranial ultrasound. Further analysis revealed that thickness of the body and splenium and the anteroposterior diameter of the genu were greater in male infants than in female infants, suggesting that there are sex differences in corpus cal osum size during the neonatal period. A second set of measurements were taken from 40 premature infants whose ges-tational age was 34 weeks or less. Corpus cal osum measurements were corrected to a gestational age of 40 weeks, and infants were grouped for analysis depending on the outcome of a neonatal behavioral neurological assessment. Compared with infants with a normal neurological assessment, corpus cal osum length and genu and splenium thicknesses were less in those with abnormalities, indicating that corpus cal osum growth in premature infants is associated with neurobehavioral de-velopment during the early extrauterine stage.

    Despite technological advances in neonatology, premature children are still susceptible to disruptions in neurological development. The current study aimed to analyze the factors that influence motor development in prematurely born school-aged children in Brazil. This cross-sectional study involved 100 "apparently normal" children, aged 8-10 years, born at less than 35 weeks of gestation or with birth weightmotor development was assessed using the Movement Assessment Battery for Children (MABC-2). The children's neuropsychological and academic performance was assessed with the Token Test (TT) and Teste de Desempenho Escolar (TDE), respectively. Parents answered questions regarding the child's clinical history and behavior using the Strengths and Difficulties Questionnaire (SDQ) and family environment resources (RAF). Hierarchical multivariate analyses revealed that 39% of the children scored lower on the MABC-2, as compared to that expected for their age (manual dexterity: 49%; balance: 35%; throwing/catching a ball: 26%). Multivariate analysis indicated that the lower the birth weight, the maternal age at childbirth, and the RAF score, the greater was the chance of impairment on the MABC-2 scores. The probability of having an impairment MABC-2 scores was four times higher when the mother was not employed. We also found associations between MABC-2 scores and the tasks of tying shoes and opening/closing zippers and buttons. Factors related to children's home environments and birth weight are associated with deficient motor performance in prematurely born Brazilian school-aged children. Deficient motor skills were also associated with difficulty in performing functional tasks requiring greater manual dexterity.

    Myelination is important perinatally and highly dependent on long-chain saturated and monounsaturated fatty acids. Long-chain polyunsaturated fatty acids, nowadays often supplemented, inhibit oleic acid synthesis. Using data from a premature cohort, we studied if nervonic, lignoceric and oleic acids correlated to growth and early development up to 18 months corrected age. Small for gestational age infants had lower concentrations than infants appropriate for gestational age. Only oleic acid was negatively correlated to long-chain polyunsaturated fatty acids. Oleic and lignoceric acids correlated to social interaction at one month, and nervonic acid to mental, psychomotor and behavioral development at 6, 10 and 18 months, also when adjusted for several confounders. Negative association between oleic acid and long-chain polyunsaturated fatty acids suggests inhibition of delta-9 desaturase, and nervonic acid´s divergent correlation to lignoceric and oleic acids suggests different metabolism in neonatal period. Our results may have implications for the supplementation of premature infants.

    Osteoarthritis (OA) is a disease affecting multiple tissues of the joints in the elderly, but most notably articular cartilage. Premature biological aging has been described in this tissue and in blood cells, suggesting a systemic component of premature aging in the pathogenesis of OA. Here, we have explored epigenetic aging in OA at the local (cartilage and bone) and systemic (blood) levels. Two DNA methylation age-measures (DmAM) were used: the multi-tissue age estimator for cartilage and bone; and a blood-specific biomarker for blood. Differences in DmAM between OA patients and controls showed an accelerated aging of 3.7 years in articular cartilage (95 % CI = 1.1 to 6.3, P = 0.008) of OA patients. By contrast, no difference in epigenetic aging was observed in bone (0.04 years; 95 % CI = −1.8 to 1.9, P = 0.3) and in blood (−0.6 years; 95 % CI = −1.5 to 0.3, P = 0.2) between OA patients and controls. Therefore, premature epigenetic aging according to DNA methylation changes was specific of OA cartilage, adding further evidence and insight on premature aging of cartilage as a component of OA pathogenesis that reflects damage and vulnerability.

The authors of this study looked longitudinally at school-age language outcomes and potential moderating variables for a group of twins born prematurely versus a control group of twins born at full term, analyzing both standardized test results and language sample data from the population-based Western Reserve Reading Project (WRRP; Petrill, Deater-Deckard, Thompson, DeThorne, & Schatschneider, 2006). Fifty-seven children born prematurely, at ≤32 weeks or children born at full term and were matched for age, gender, race, and parental education. Data included discourse-level language samples and standardized test results, collected at average ages 7, 8, and 10 years. The language samples were analyzed to yield a number of semantic and syntactic measures that were consolidated via factor analysis. Regression models showed significant differences between the 2 groups for standardized test results, although the mean score for both groups fell in the normal range. For the discourse-level language measures, however, differences never reached statistical significance. Parental education was significantly associated with improved standardized test scores. These findings suggest that in the absence of frank neurological impairment, sophisticated semantic and syntactic skills may be relatively intact in the discourse-level language of children born prematurely. Implications for assessment, particularly the potential role of attention and executive function in standardized testing tasks, are reviewed.

    Full Text Available BACKGROUND The objectives of this study are 1 To find out the incidence of premature rupture of membranes, 2 To evaluate the aetiology of premature rupture of membranes, 3 To assess foetal and maternal outcome in premature rupture of membranes. MATERIAL AND METHODS This prospective case control study was conducted in Govt. RSRM Lying In Hospital, Chennai, over a period of 6 months and 100 cases of spontaneous rupture of membranes attending the Department of Obstetrics and Gynaecology were studied. Maternal and neonatal outcome were compared with controls. RESULTS Incidence of PROM was 9.06%. Most of them belonged to low socioeconomic class and in the age group 20-29 years, commonly seen primi gravida and in unbooked cases. Aetiological analysis revealed infection in 15% of cases, which is evident by positive amniotic fluid culture, h/o recent coitus in 20%, mal-presentation in 7%. Cause is unknown in most of the cases. The caesarean section rate is 24% when compared to 12% in control group. The PROM group had higher morbidities like postpartum haemorrhage, postpartum fever, wound infection, neonatal sepsis. CONCLUSION This study showed significantly increased morbidity for both mother and baby. PROM causes major increase in the incidence of prematurity, hence careful screening of high risk factors and treatment of infection promptly is needed to decrease the perinatal morbidity and mortality.

    The authors describe a case of a premature infant born with a parietal skull depression who suffered an intraventricular hemorrhage and an ipsilateral intracerebral injury. At 21 months of life the infant's gross motor milestones were delayed and he had moderate spastic hemiplegia. Although skull depressions at birth are usually benign, they may be associated with long-term neurologic sequelae.

    To evaluate the influence of oral motor skills of premature infants on their oral feeding performance and growth, during neonatal hospitalization. Fifty-one newborns hospitalized in the neonatal intensive care unit of a hospital in Southern Brazil, between July 2012 and March 2013, were evaluated. The evaluation of oral feeding skills, according to Lau and Smith, was applied after prescription for starting oral feeding. The oral feeding performance was analyzed using the following variables: days taken to start independent oral feeding and hospital discharge. Growth was measured by weight, length, and head circumference, using the curves of Fenton, at birth, first and independent oral feeding, and hospital discharge. At birth, 71% preterm infants were proper for gestational age, most of them were males (53%), with average of 33.6 (±1.5) weeks of gestational age. The gestational age in the assessment did not influence the oral feeding performance of the premature infant and did not differ between levels. Time of transition from tube feeding to oral feeding and hospital stay was shorter when the oral skills were higher. At birth, there was a tendency of low weight and low oral feeding performance. Level IV premature infants in the release of oral feeding presented higher weights. The level of oral skills of the premature infant interfered positively on time of feeding transition from tube to independent oral feeding and hospital stay. Growth, represented by weight gain, was not affected by the level of oral skill.

    2016-08-01

    The term 'Patient Reported Outcome', abbreviated as PRO, was introduced by the US Food and Drug Administration (FDA) which proposed guidance on the development and validation of PROs. Previously PROs were known as self-report diaries, event-logs, self-administered questionnaires, and clinician administered rating scales. PROs seek to capture the subjective perceptions of patients and/or partner's related to their specific symptoms, degree of bother, efficacy of a medication or psychotherapy intervention, and quality of life issues related to a specific condition. This article reviews the essential psychometric and regulatory agency requirements in the development of PROs. The constructs of reliability, various forms of validity, sensitivity, and specificity as well as concerns with translating a PRO into a different language are reviewed. Three PROs, the Premature Ejaculation Profile (PEP), the Index of Premature Ejaculation (IPE) and the Premature Ejaculation Diagnostic Tool (PEDT) all used in the assessment of premature ejaculation (PE) are discussed. These questionnaires meet or exceed all the psychometric requirements and have been employed in clinical trials and observational studies of men with PE. The article concludes on discussing some of the limitations of PRO use and recommendations for the future.

    Full Text Available Objective: to reveal the factors that are responsible for the development of respiratory distress syndrome (RDS and the specific features of its course in preterm twin neonates. Subjects and methods. Twenty-three patients who had had twin pregnancy, including 9 (39.1% and 14 (60% with monochorial and bichorial biamniotic twin pregnancies, respectively, were examined. Their mean age was 28.5±5.4 years. Obstetric and gynecologic histories, conditions at conception, the course of pregnancy, the type of pla-centation, and fetal presentation were considered. The placentas were morphologically examined. In all the patients, pregnancy ended in birth of 46 premature neonates, of them there were 19 (41.3% boys and 27 (58.7% girls. The gestational age of the neonates averaged 31.7±2.3 weeks. The evaluation of the efficiency of performed therapy used clinical assessment of the status of the premature neonates; measurement of partial oxygen tension (pO2 and calculation of alveolar-arterial oxygen gradient (A-a DO2, respiratory index (RI, and oxygenation index (OI; death rates were analyzed. Results. The main cause of respiratory failure (RF was RDS in premature twins. Neonatal blood aspiration-caused pneumonia occurred in one case. The course of RDS was variable. Most neonatal infants needed exogenous surfactant replacement therapy and mechanical ventilation (MV. No signs of RF were present in 7 (15.2% premature neonates. Conclusion. Premature twins are a high RDS risk group. The unfavorable factors that contribute to the development of the disease are multiple pregnancy, a past maternal obstetric history, in-vitro fertilization-induced pregnancy, severe gestosis in the second half of pregnancy, and preterm delivery. The type of placentation affects the fetal status after birth. Fatal outcome occurred in infants from the monochorial bioamniotic twins. In multiple pregnancies, there are pathological changes in the placenta, its membranes, and umbilical

    Full Text Available The term encephalopathy of prematurity encompasses not only the acute brain injury (such as intraventricular hemorrhage but also complex disturbance on the infant’s subsequent brain development. In premature infants, the most frequent recognized source of brain injury is intraventricular hemorrhage (IVH and periventricular leukomalacia (PVL. Furthermore 20-25% infants with birth weigh less than 1,500 g will have IVH and that proportion increases to 45% if the birth weight is less than 500-750 g. In addition, nearly 60% of very low birth weight newborns will have hypoxic-ischemic injury. Therefore permanent lifetime neurodevelopmental disabilities are frequent in premature infants. Innovative approach to prevent or decrease brain injury in preterm infants requires discovery of biomarkers able to discriminate infants at risk for injury, monitor the progression of the injury and assess efficacy of neuroprotective clinical trials. In this article, we will review biomarkers studied in premature infants with IVH, Post-hemorrhagic ventricular dilation (PHVD and PVL including: S100b, Activin A, erythropoietin, chemokine CCL 18, GFAP and NFL will also be examined. Some of the most promising biomarkers for IVH are S100β and Activin. The concentrations of TGF-β1, MMP-9 and PAI-1 in cerebrospinal fluid could be used to discriminate patients that will require shunt after post-hemorrhagic ventricular dilation. Neonatal brain injury is frequent in premature infants admitted to the neonatal intensive care and we hope to contribute to the awareness and interest in clinical validation of established as well as novel neonatal brain injury biomarkers.

    Introduction: Anemia in preterm infants is the pathophysiological process with greater and more rapid decline in hemoglobin compared to the physiological anemia in infants. There is a need for transfusions and administration of human recombinant erythropoietin. Aim: To determine the frequency of anemia in premature infants at the Pediatric Clinic, University Clinical Center Sarajevo, as well as parameter values in the blood count of premature infants and to explore a relationship between blood transfusions with the advent of intraventricular hemorrhage (determine treatment outcome in preterm infants). Patients and methods: Research is retrospective study and it included the period of six months in year 2014. Research included 100 patients, gestational age < 37 weeks (premature infants). Data were collected by examining the medical records of patients at the Pediatric Clinic, UCCS. Results: The first group of patients were premature infants of gestational age ≤ 32 weeks (62/100) and the second group were premature infants of gestational age 33-37 weeks (38/100). Among the patients, 5% were boys and 46% girls. There was significant difference in birth weight and APGAR score among the groups. In the first group, there were 27.42% of deaths, while in the second group, there were only 10.53% of deaths. There was a significant difference in the length of treatment. There was a statistically significant difference in the need for transfusion among the groups. 18 patients in the first group required a transfusion, while in the second group only 3 patients. Conclusions: Preterm infants of gestational age ≤ 32 weeks are likely candidates for blood transfusion during treatment. Preterm infants of gestational age ≤ 32 weeks have the risk of intracranial bleeding associated with the application of blood transfusion in the first week of life. PMID:28210010

    Full Text Available Introduction: To determine the rate, etiology and morbidity association of disorders of thyroid function tests (TFTs in premature babies. Materials and Methods: A total of 139 premature babies who were admitted to Uludag University Faculty of Medicine Hospital Neonatal Intensive Care Unit between January 2009 and January 2012 were included in this study. Prenatal, natal and postnatal characteristics along with TFTs results were recorded. TFTs were performed for all patients in the first and third weeks of life. Thyroid stimulation hormone (TSH values of >10 IU/L was considered elevated. Free T3 and T4 levels were evaluated according to laboratory cut-off values. Weight, height and head circumference values of all individuals with and without the diagnosis of hypothyroidism on the 6th, 12th, and 18th months of their polyclinic follow-ups.Results: Abnormal TFTs were detected in 41 (24% patients. Twenty two patients (53% had transient TSH elevation, 9 (22% had primary hypothyroidism, 9 (22% had non-thyroidal disease and 1 (2.4% had transient hypothyroxinemia. Among morbidities, respiratory distress syndrome rate was found to be significantly higher in patients with thyroid function disorders (p=0.007. The rate of thyroid function disorders in patients with mothers with hypothyroidism was significantly more frequent compared to patients without maternal hypothyroidism (p=0.049. The mean head circumference in 18 month was significantly lower in patients with abnormal TFTs (p=0.047. Conclusions: Thyroid function disorders are common morbidities in premature babies and are important for neuromotor development. Maternal thyroid function disorder can lead to impairment of TFTs in infants. Thyroid function tests should be performed in all premature babies and hypotyhroidism should be treated. Avoidance of iodine exposure in premature infants can reduce the rate of abnormal TFTs and transient hypothyroidism.

    All types of memory disorders have been observed in children, although these reports are rare. Developmental amnesia selectively involves episodic daily life memory while semantic learning is respected and general intelligence is not affected. Daily life is severely disturbed by this cognitive disorder usually occurring after hypoxic ischemic injury with bilateral hippocampal atrophy on MRI. Memory disorders are underdiagnosed in at-risk patients and rarely reported. We report on a former small-for-gestational-age preterm infant with no obvious hypoxic event during perinatal life. The follow-up was normal until elementary school. He had to spend 2 years in 1st grade and exhibited some behavioral troubles. At the age of 9, he was suspected of suffering from dyspraxia and was referred to a pediatrics rehabilitation center. IQ and neuropsychological tests were administered and showed selective autobiographical memory impairment defining developmental amnesia. Despite a typical clinical presentation, brain MRI was normal, including the hippocampal area. This observation underlines the need for a prolonged follow-up until school age to assess the outcome of preterm infants. Otherwise, the evaluation will be limited to motor impairment. Particular attention should be paid to memory during the follow-up to avoid misdiagnoses and to plan and adapt these children's educational strategies. Copyright 2009 Elsevier Masson SAS.

    Preterm birth is a risk factor for deficits of neurological and cognitive development. Four cohort studies are reported investigating the effects of very premature birth (development correlated with the severity of brain abnormality observed on structural MRI at and before term, and were sensitive predictors of neurodevelopmental outcome at 2 years. The second study compared VERP measures for orientation-reversal and direction-reversal (DR) stimuli, from 2 to 5 months post-term age, in healthy very premature infants compared to infants born at term. The groups did not differ on the development of OR-VERP responses, but the development of the DR-VERP motion responses was delayed in the premature group despite the absence of any brain damage visible on ultrasound, consistent with the developmental vulnerability we have identified in the dorsal cortical stream. The third study used the Atkinson Battery of Child Development for Examining Functional Vision (ABCDEFV) to assess sensory, perceptual, cognitive and spatial visual functions, together with preschool tests of attention and executive function. The premature group showed delays on these tests in line with severity of observed perinatal brain damage on structural MRI at term age. Deficits on certain spatial tasks (e.g. block-construction copying) and executive function tests (e.g. the detour box task) were apparent even in children with minimal damage apparent on MRI. The fourth study tested a large cohort of 6- to 7-year old children born before 32 weeks gestation, across a wide range of cognitive domains, including new tests of spatial cognition and memory. The premature group as a whole showed significant deficits on both auditory and visual tests of attention and attentional control from the TEA-Ch battery, on tests of location memory, block construction and on many visuocognitive and visuomotor tests. Development was generally relatively normal on language tests and on WPPSI scores. Factor analysis showed

    Preterm birth is a difficult situation for all family members, interfering with the establishment of parental bonding and attachment with the baby. This paper is a qualitative and collective case study, carried out with the purpose of identifying the perception of mothers concerning the maintenance of lactation during the hospital stay of premature infants at Hospital de Clínicas de Porto Alegre (Clinic Hospital of Porto Alegre), Rio Grande do Sul, Brazil. The data were collected from March to April/2006 through interviews and observations and resulted in four categories. This article focuses only on the categories that refer to the mechanisms used by mothers to maintain lactation during hospitalization: beliefs and attitudes related to maintenance of lactation and breast milk expression at the human milk bank. The maintenance of lactation constitutes a complex process to be learnt by mothers involved with their infant's prematurity and hospitalization.

    The present case study reports a case of chronic cough and cough syncope associated with frequent premature ventricular complexes (PVCs). Careful analysis of cough-related symptoms and ECG monitoring led to the suspicion of PVC-induced cough. A coincidence between PVCs and episodes of cough was also documented by a portable multichannel recorder. Moreover, Doppler echocardiography revealed a PVC-induced transient increase in the pulmonary artery blood flow. After exclusion of other possible aetiologies, complete relief of chronic cough and cough syncope was achieved by radiofrequency ablation of the arrhythmogenic focus located in the right ventricular outflow tract. Premature ventricular complexes should be considered as a cause of chronic cough and cough syncope and an interdisciplinary cooperation can lead to successful diagnosis and treatment of this condition.

    Of 99 children in the Royal Blind School, Edinburgh (which serves Scotland and part of N E England), 15 had optic atrophy (hydrocephalus 4, intracranial haemorrhage 2, prematurity 2, fetal distress 2, birth asphyxia 2, cerebral atrophy 1, cardiac arrest during hernia operation 1, and leukaemia 1). Fourteen had congenital cataract, 12 congenital retinal aplasia (Leber's congenital amaurosis) and 11 retinopathy of prematurity. There were small numbers in many other diagnostic categories, including three with non-accidental head injury. Mental retardation, spasticity, and nystagmus were frequent other correlates in all diagnostic categories. 'Very probably hereditary' was a conservative attribution in 36, while 'probable' seemed appropriate for 12-that is, almost 48% were hereditary. Only about 11 cases might have been prevented through genetic counselling, which testifies to the frequency of autosomal recessive hereditary disease, although no parents were consanguineous.

    The Chediak-Higashi syndrome (CHS) is a rare hereditary fatal disease, if not treated. These changes are associated with various diseases and syndromes that mainly cause periodontal disease and thus the premature loss of teeth. This paper describes the monitoring of premature loss of primary teeth that began when the child was 5 years old. On presentation his teeth were mobile and there was a history of gingival bleeding. Panoramic radiography revealed generalized and severe bone loss, and the teeth showed no bony support enough for their stability. Blood test was ordered to assess the overall health of the child and giant cells with cytoplasmic granules were found, confirming the diagnosis of CHS. The management of periodontal disease focused on the control of infection and bacterial plaque by mechanical and chemical methods.

    The aim of this pilot research was to investigate whether infants of mothers with panic disorder (PD) would be at higher risk for prematurity and low birth weight (corrected for gestational age) than controls. Medical records were reviewed for 25 mothers with PD and 33 mothers without a lifetime history of anxiety disorders or other major psychopathology as determined by diagnostic interview. Mothers also completed questionnaires concerning demographic information and life stresses. Compared to controls, infants with PD mothers were not significantly more likely to be born prematurely or earlier than controls but did show smaller birth weight corrected for gestational age, even after accounting for possible confounding influences. Additional research is needed to confirm these preliminary findings. Studying PD mothers during pregnancy could provide insight concerning mechanisms for the development of low birth weight and psychopathology.

    Premature ejaculation (PE) is one of the commonest male sexual dysfunctions. It is characterized by ejaculation which occurs before or soon after vaginal penetration, which causes significant psychological distress to the individual, and his partner. The exact cause of PE is still unknown but several mechanisms are proposed, and these involve complex interactions of neurophysiological, psychosocial, and cognitive factors. We discuss the role of serotonin, nitric oxide, phosphodiesterase enzymes and other neurotransmitters. Treatment of PE tends to co-occur with other sexual difficulties, especially erectile dysfunction (ED). Treatment with selective serotonin reuptake inhibitors (SSRIs) and Dapoxitene are also discussed in detail. The treatment strategy requires a comprehensive holistic approach incorporating both combination of psychopharmacological agent and cognitive-behavioral therapy (CBT). The present review highlights the integration of the hypothalamic-neural and reverberating emotional circuit and discusses the etiology and treatment for patients with PE.

    Perinatal hypoxic-ischemic brain damage is a major cause of neuronal and behavior deficits, in which the onset of injury can be before, at or after birth, and the effects may be delayed. Pontosubicular neuron necrosis (PSN) is one of perinatal hypoxic-ischemic brain injury and its pathological peculiarity is neuronal apoptosis. In this study, we investigated whether apoptotic cascade of PSN used a caspase-pathway or not, and whether hypoglycemia activated apoptosis or not. Sections of the pons of PSN with and without hypoglycemia were stained using terminal deoxynucleotidyl transferase-mediated deoxyuridine triphosphate nick end labeling (TUNEL) and immunohistochemistry for glial fibrillary acidic protein (GFAP), Bcl-2, Bcl-x and activated caspase 3. Additionally, we performed immunoblot analysis of Bcl-2, Bcl-x and activated caspase 3. TUNEL-positive cell was closely associated with the presence of karyorrhexis. Under combination of karyorrhectic and TUNEL-positive cells, number of apoptotic cells in premature brains was significantly more than in mature brains. Hypoxic-ischemic brain injury was considered to easily lead to apoptosis in premature infants. Moreover, as this pathophysiology, caspase-pathway activation contributed to neuronal death from caspase-immunoexpression analyses. PSN with hypoglycemia showed large number of apoptotic cells and higher expression of activated caspase 3. The result may be more severe with the background of hypoglycemia and prematurity complicated by hypoxia and/or ischemia.

    Full Text Available Support of long-term breast feeding is a pressing issue of neonatology. It is known that the unique composition of breast milk ensures proper physical and neuropsychic development of infants, as it contains all the necessary nutrients in the sufficient amount and optimal proportion. The authors gave specific attention to provision of premature infants, especially with very low and extremely low birth weight, with breast milk. However, it is very difficult to launch and maintain breast feeding in this very category of patients. There are many reasons impeding adequate provision of premature infants with breast milk. The main problem on the part of the mother is hypogalactia, which may be caused by preterm labor stress, lack of confidence in successful lactation, temporary medical contraindications and, therefore, deviant formation of the lactation dominant, motivation towards prolonged breast feeding etc. On the part of the child: severe condition, no or weak sucking reflex, often — prolonged parenteral and tube feeding, need in supplementary feeding. The article presents published data on various methods of maintaining breast feeding at the stage of hospital developmental care of premature infants and experience of breast feeding support accumulated at the Scientific Center of Children’s Health, which proves that simultaneous support and follow-up of the child’s mother and her family in whole by several specialists (neonatologist/pediatrician, psychologist, breast physician, dietician and recreation therapist not only at the stages of labor and development care, but also after discharge from hospital are required to ensure rational and prolonged breast feeding of premature infants and normal growth and development thereof.

    Objectives The life expectancy gap between Central‐Eastern European (CEE) countries, including Hungary, and Western Europe (WE) is mainly attributable to excess cardiovascular (CV) mortality in midlife. This study explores the contribution of socioeconomic, work related, psychosocial, and behavioural variables to explaining variations of middle aged male and female CV mortality across 150 sub‐regions in Hungary. Design Cross sectional, ecological analyses. Setting 150 sub‐regions of Hungary. Participants and methods 12 643 people were interviewed in Hungarostudy 2002 survey, representing the Hungarian population according to sex, age, and sub‐regions. Independent variables were income, education, control in work, job insecurity, weekend working hours, social support, depression, hostility, anomie, smoking, body mass index, and alcohol misuse. Main outcome measures Gender specific standardised premature (45–64 years) total CV, ischaemic heart disease, and cerebrovascular mortality rates in 150 sub‐regions of Hungary. Results Low education and income were the most important determinants of mid‐aged CV mortality differences across sub‐regions. High weekend workload, low social support at work, and low control at work account for a large part of variation in male premature CV mortality rates, whereas job insecurity, high weekend workload, and low control at work contribute most noticeably to variations in premature CV mortality rates among women. Low social support from friends, depression, anomie, hostility, alcohol misuse and cigarette smoking can also explain a considerable part of variations of premature CV mortality differences. Conclusion Variations in middle aged CV mortality rates in a rapidly changing society in CEE are largely accounted for by distinct unfavourable working and other psychosocial stress conditions.

    Full Text Available Introduction The research in long latency auditory evokes potentials (LLAEP in newborns is recent because of the cortical structure maturation, but studies note that these potentials may be evidenced at this age and could be considered as indicators of cognitive development. Purpose To research the exogenous potentials in term and premature infants during their first month of life. Materials and Methods The sample consisted of 25 newborns, 15 term and 10 premature infants. The infants with gestational age under 37 weeks were considered premature. To evaluate the cortical potentials, the infants remained in natural sleep. The LLAEPs were researched binaurally, through insertion earphones, with frequent /ba/ and rare /ga/ speech stimuli in the intensity of 80 dB HL (decibel hearing level. The frequent stimuli presented a total of 80% of the presentations, and the rare, 20%. The data were statistically analyzed. Results The average gestational age of the term infants was 38.9 weeks (± 1.3 and for the premature group, 33.9 weeks (± 1.6. It was possible to observe only the potentials P1 and N1 in both groups, but there was no statistically significant difference for the latencies of the components P1 and N1 (p > 0.05 between the groups. Conclusion It was possible to observe the exogenous components P1 and N1 of the cortical potentials in both term and preterm newborns of no more than 1 month of age. However, there was no difference between the groups.

    Full Text Available The gynecological and reproductive histories of 193 women from fragile X families were surveyed. Among the 101 carriers of the premutation, 14 experienced premature menopause, contrarily to their 37 fully mutated and 55 noncarrier female relatives. Although premature menopause showed a tendency to cluster in certain fragile X families, as a group, the premutated women experienced menopause earlier than noncarriers. This suggests that premature menopause may be the extreme effect of a spectrum of ovarian anomalies associated with the fragile X premutation.Entrevistamos 193 mulheres de famílias com afetados pela síndrome do cromossomo X frágil, quanto a sua história ginecológica e reprodutiva. Entre as 101 portadoras da pré-mutação, 14 tiveram menopausa precoce, mas nenhuma das 37 portadoras da mutação completa ou das 55 não portadoras apresentaram esta anomalia. Observamos uma tendência para a concentração da menopausa precoce em certas famílias, o que poderia significar uma peculiariedade de certas pré-mutações. Entretanto, o fato de as mulheres pré-mutadas tenderem a entrar em menopausa mais cedo do que as não portadoras sugere que a menopausa precoce seja o extremo do espectro de efeitos ovarianos da pré-mutação.

The traditional perception has been patient discontinuation is mainly driven by unwanted side effects. Systematic analysis of data from clinical trials across several disease states was performed to identify predictors of premature discontinuation during clinical interventions.Methods: A post hoc analysis was conducted on 22 randomized, double-blind, placebo-controlled clinical trials for treatment of fibromyalgia, diabetic peripheral neuropathic pain, major depressive disorder, and generalized anxiety disorder. Analyses were conducted on pooled data within each disease state.Results: Lack of early therapeutic response was a significant predictor of patient discontinuation in each disease state. Visit-wise changes in therapeutic response and severity of adverse events were also significant risk factors, with change in therapeutic response having a higher significance level in three disease states. Patients who discontinued due to adverse events had similar therapeutic responses as patients completing treatment.Conclusion: Contrary to the conventional belief that premature treatment discontinuation is primarily related to adverse events, our findings suggest lack of therapeutic response also plays a significant role in patient attrition. This research highlights the importance of systematic monitoring of therapeutic response in clinical practice as a measure to prevent patients’ discontinuation from pharmacological treatments.Keywords: attrition, depression, generalized anxiety disorder, fibromyalgia, therapeutic response, adverse event

    Mendel's name more than of any other draws our attention to the personal side in terms of success and failure in science. Mendel lived 19 years after presenting his research findings and died without receiving any recognition for his work. Are premature discoveries things of the past, you may ask? I review the material basis of science in terms of science boundary and field accessibility and analyze the possibility of premature discoveries in different fields of science such as, for example, physics and biology. I conclude that science has reached a stage where progress is being made mostly by pushing the boundary of the known from inside than by leaping across boundaries. As more researchers become engaged in science, and as more publications become open access, on-line, and interactive, the probability of an important discovery remaining buried and going unrecognized would become exceedingly small. Of course, as examples from physics show, a new theory or an important idea can always lie low, unrecognized until it becomes re-discovered and popularized by other researchers. Thus, premature discoveries will become less likely but not forbidden.

    Centric relation prematurities of frontal teeth are frequently found with patients who have severe orthodontic anomalies or received extensive restorative treatment. They can cause a range of symptoms ranging from loosening of the teeth to temporomandibular disorders (TMD). The objective of this work has been to derive a mathematical description of the mandibular and periodontal forces generated by anterior prematurities for different incisor relations. In order to quantify the effect of contact area (location and inclination) and the tooth inclination, a two-dimensional mathematical approach was used. Vectorisation of the forces and bending moments makes it possible to predict under which conditions the load increase mainly affecting the anterior teeth can and may cause localized pain and eventually loosening and flaring/crowding of the upper/lower incisors and under which conditions the temporomandibular joint will suffer a large increase in retrusive force, which potentially leads to TMD. For 10 patients with anterior prematurities, analysis of the incisor relation was carried out. For all cases the conclusions drawn from the mathematical model were in full agreement with the reported symptoms, which could be successfully treated.

    In this retrospective study, the relationship between demographic characteristics, past medical history, general lifestyle habits and susceptibility of premature ovarian failure (POF) in Han Chinese population was investigated. Five hundred and fifty-three patients with POF and 400 women with normal ovarian function were recruited. A questionnaire was designed to gather information from responders. Logistic regression was carried out to calculate odds ratios (OR), 95% confidence intervals (95% CI) and P-values. History of pelvic surgery, mumps, having relatives with menstrual abnormalities and exposure to chemical agents were significantly associated with increased risk of POF (OR 5.53 [2.15 to 14.23]; 3.26 [2.38 to 4.47]; 28.12 [8.84 to 89.46]; 4.47 [2.09 to 9.58]). Vegetarian diet, tea and mineral water consumption reduced the risk of POF (OR 0.27 [0.19 to 0.37]; 0.04 [0.03 to 0.07]; 0.63 [0.47 to 0.85], respectively). Heredity, pelvic surgery, mumps and exposure to chemical agents were identified as risk factors for POF, whereas vegetarian diet, tea consumption and mineral water drinking were protective. Therefore, genetic consultation could help those women whose relatives manifested an early or premature menopause to avoid the consequences of possible premature ovarian function cessation. Avoidance of exposure to endocrine disrupters and flavonoids intake should be considered.

    Contemporary clinical practice for the care of the prematurely born babies has markedly improved their rates of survival so that most of these babies are expected to grow up to live a healthy functional life. Since the clinical follow up is of short duration (years), only limited data are available to relate non-communicable diseases in adult life to events and interventions in the neonatal period. The major events that could have a programming effect include (1) Intrauterine growth restriction (2) Interruption of pregnancy with change in redox and reactive oxygen species injury (3) Nutritional and pharmacological protocols for Clinical care (4) Nutritional care in the first two years resulting in accelerated weight gain. The available data are discussed in the context of perturbations in one carbon (methyl transfer) metabolism and its possible programming effects. Although direct evidence for genomic methylation is not available, clinical and experimental data on impact of redox and ROS, of low protein intake, excess methionine load and vitamin A, on methyl transfers are reviewed. The consequences of antenatal and postnatal administration of glucocorticoids are presented. Analysis of the correlates of insulin sensitivity at older age, suggests that premature birth is the major contributor, and is compounded by gain in weight during infancy. We speculate that premature interruption of pregnancy and neonatal interventions by effecting one carbon metabolism may cause programming effects on the immature baby. These can be additive to the effects of intrauterine environment (growth restriction) and are compounded by accelerated growth in early infancy. PMID:25054678

    Full Text Available Fabio Coppedè Department of Translational Research and New Technologies in Medicine and Surgery, University of Pisa, Pisa, Italy Abstract: Hutchinson–Gilford Progeria Syndrome and Werner syndrome, also known as childhood- and adulthood-progeria, respectively, represent two of the best characterized human progeroid diseases with clinical features mimicking physiological aging at an early age. The discovery of their genetic basis has led to the identification of several gene mutations leading to a spectrum of progeroid phenotypes ranging from moderate and mild–severe to very aggressive forms. In parallel, the creation of disease registers and databases provided available data for the design of relatively large-scale epidemiological studies, thereby allowing a better understanding of the nature and frequency of the premature aging-associated signs and symptoms. The aim of this article is to review the most recent findings concerning the epidemiology of premature aging disorders, their genetic basis, and the most recent reports on the frequency of associated diseases.

    To determine the cost-effectiveness of treatment with caffeine compared with placebo for apnea of prematurity in infants with birth weights less than 1250 g, from birth through 18 to 21 months' corrected age. We undertook a retrospective economic evaluation of the cost per survivor without neurodevelopmental impairment by using individual-patient data from the Caffeine for Apnea of Prematurity clinical trial (N = 1869). We included direct medical costs either to the insurance payer or the hospital but excluded costs to parents and society, such as lost productivity. We used a price of $0.21/mg of generic caffeine citrate for our base-case analysis. All costs were expressed in 2008 Canadian dollars and discounted at 3%. The time horizon for this analysis extended through 18 to 21 months' corrected age to match the clinical trial. The mean cost per infant was $124 466 in the caffeine group and $133 505 in the placebo group (difference: $9039 [-14 749 to -3375]; adjusted P = .014). Cost-effectiveness analysis showed caffeine to be a dominant or "win-win" therapy: in >99% of 1000 bootstrap replications of the analysis, caffeine-treated infants had simultaneously better outcomes and lower mean costs. These results were robust to a 1000% increase in the individual resource items, including the price of caffeine citrate. In comparison with placebo, caffeine therapy for apnea of prematurity in infants weighing less than 1250 g is economically appealing for infants up to 18 to 21 months' corrected age.

    Background. In premature infants, maintaining blood partial pressure of carbon dioxide (pCO2) value within a narrow range is important to avoid cerebral lesions. The aim of this study was to assess the accuracy of a noninvasive transcutaneous method (TcpCO2), compared to blood partial pressure of carbon dioxide (pCO2). Methods. Retrospective observational study in a tertiary neonatal intensive care unit. We analyzed the correlation between blood pCO2 and transcutaneous values and the accuracy between the trends of blood pCO2 and TcpCO2 in all consecutive premature infants born at <33 weeks' gestational age. Results. 248 infants were included (median gestational age: 29 + 5 weeks and median birth weight: 1250 g), providing 1365 pairs of TcpCO2 and blood pCO2 values. Pearson's R correlation between these values was 0.58. The mean bias was -0.93 kPa with a 95% confidence limit of agreement of -4.05 to +2.16 kPa. Correlation between the trends of TcpCO2 and blood pCO2 values was good in only 39.6%. Conclusions. In premature infants, TcpCO2 was poorly correlated to blood pCO2, with a wide limit of agreement. Furthermore, concordance between trends was equally low. We warn about clinical decision-making on TcpCO2 alone when used as continuous monitoring.

    Objective Unexplained clitoromegaly is a rare but well recognised feature in girls born premature. Although detected at birth, girls may re-present during childhood to paediatric urologists and gynaecologists who should be aware of this condition. The aim of the study was to describe the clinical findings and management of a series of girls presenting with persistent congenital clitoromegaly associated with prematurity. Materials and methods This was a retrospective notes review set in a tertiary referral centre for Paediatric and Adolescent Gynaecology (PAG). Results Eight girls with a mean age of 6 years were seen over an eight year period. In all cases a Disorder of Sex Development (DSD) had been previously excluded. The main symptoms were discomfort or concern about appearance. On examination five girls had excess skin over the clitoris and three had enlarged corporal tissue. Management included reassurance and simple measures to ease discomfort. In two cases the parents requested referral to a paediatric urologist to consider clitoral surgery. Conclusion As survival rates for extreme prematurity improve, paediatric urologists and gynaecologists are likely to see more of these cases. Clinicians must be familiar with this condition to ensure children are managed appropriately. PMID:23619354

    To evaluate the incidence of MRI-related claustrophobia and prematurely terminated MRI (ptMRI) examinations due to claustrophobia in a large-scale cohort study. The hospital's computerized radiology information system (RIS) was retrospectively analyzed for all 1.5-Tesla MRI examinations and reports during the year 2004. Data collected included demographic information, body part examined, known claustrophobia, and whether the examination was prematurely terminated. All information available on the MRI examinations and the patient-based data (i.e., excluding any additional examinations per patient) were analyzed. A total of 5798 MRI reports of 4821 patients were evaluated. A total of 95 patients (1.97%) suffered from claustrophobia and 59 (1.22%) prematurely terminated the examination due to claustrophobia. The incidence of ptMRI was higher in women than men (no statistical significance). The majority of patients with ptMRI were between 20 and 80 years old. Patients undergoing head MRI showed the highest incidence of ptMRI and those undergoing extremity, breast, or pelvic MRI had the lowest. Prone compared to supine positioning results in the lowest ptMRI incidence (P Claustrophobic reactions cause a relatively low incidence of ptMRI and are influenced by sex, body part examined, and positioning within the MR scanner. Sedation and prone positioning might help overcome these reactions. (c) 2007 Wiley-Liss, Inc.

    This retrospective study was conducted to explore rates, timing and predictors of two forms of premature termination of treatment (PTT) in an inpatient eating disorders programme: patient dropout (DO) and administrative discharge (AD). A chart review was conducted to obtain demographic, Eating Disorder Inventory-2 (EDI-2), and Resident Assessment Instrument-Mental Health (RAI-MH) data for 186 patients being treated for bulimia nervosa (BN), anorexia nervosa (AN), or eating disorder not otherwise specified (EDNOS). Overall, of the 37.6% of patients who terminated treatment prematurely, 22.1% of patients dropped out, and 15.5% of patients were administratively discharged. Time at which discharge occurred was found to be associated with the type of premature termination. The presence of DSM-IV Axis-I comorbidity was found to be the only factor associated with an increased risk of being administratively discharged. No factors were predictive of patients dropping out of treatment. The findings support the notion that AD and patient DO are different events that may have different factors influencing their rates and timing. Implications for future research and programme planning are discussed.

    Full Text Available The development of an affectionate parent-infant bond is essential for a newborn infant's survival and development. However, from evolutionary theory it can be derived that parental bonding is not an automatic process, but dependent on infants' cues to reproductive potential and parents' access to resources. The purpose of the present study was to examine the process of bonding in a sample of Dutch mothers (n = 200 and fathers (n = 193 of full-term (n = 69, moderately premature (n = 68, and very premature infants (n = 63. During the first month postpartum parents completed the Pictorial Representation of Attachment Measure (PRAM and Postpartum Bonding Questionnaire (PBQ. Longitudinal analyses revealed that mothers' PRAM scores decreased after moderately preterm delivery, whereas decreases in PRAM scores occurred in both parents after very preterm delivery. As lower PRAM scores represent stronger feelings of parent-infant connectedness, our findings suggest a higher degree of bonding after premature childbirth. Results of the PBQ analysis were in line with PRAM outcomes, as parents of preterm infants reported less bonding problems compared to parents of full-terms. These findings support the hypothesis that in affluent countries with adequate resources, bonding in parents of preterm infants on average may be higher than in parents of full-term infants.

    To examine the feasibility of a retinopathy of prematurity (ROP) telemedicine evaluation system of providing timely feedback to a neonatal intensive care unit (NICU) with at-risk premature infants. This was a prospective observational study of premature infants with birth weights of return of the grading results to the clinical center was 10.1 ± 11.3 hours (standard deviation), with a median of 12.0 hours (1st quartile, 0.9 hours; 3rd quartile, 16 hours). Overall, 95.5% of gradings (95% CI, 93.9%-96.7%) were returned within 24 hours. Subgroup analyses found, for image sets submitted to the reading center before 2 p.m. Eastern Standard Time, median time to report was 1.7 hours (1st quartile, 0.7 hours; 3rd quartile, 15.5 hours) compared with those submitted after 2pm (median, 14.1 hours; 1st quartile, 11.2, hours; 3rd quartile, 16.3 hours). An ROP telemedicine approach can provide timely feedback to the NICU regarding the detection of potentially serious ROP and thus referral to an ophthalmologist for examination and consideration of treatment.

    Contemporary clinical practice for the care of the prematurely born babies has markedly improved their rates of survival so that most of these babies are expected to grow up to live a healthy functional life. Since the clinical follow-up is of short duration (years), only limited data are available to relate non-communicable diseases in adult life to events and interventions in the neonatal period. The major events that could have a programming effect include: (1) intrauterine growth restriction; (2) interruption of pregnancy with change in redox and reactive oxygen species (ROS) injury; (3) nutritional and pharmacological protocols for clinical care; and (4) nutritional care in the first 2 years resulting in accelerated weight gain. The available data are discussed in the context of perturbations in one carbon (methyl transfer) metabolism and its possible programming effects. Although direct evidence for genomic methylation is not available, clinical and experimental data on impact of redox and ROS, of low protein intake, excess methionine load and vitamin A, on methyl transfers are reviewed. The consequences of antenatal and postnatal administration of glucocorticoids are presented. Analysis of the correlates of insulin sensitivity at older age, suggests that premature birth is the major contributor, and is compounded by gain in weight during infancy. We speculate that premature interruption of pregnancy and neonatal interventions by affecting one carbon metabolism may cause programming effects on the immature baby. These can be additive to the effects of intrauterine environment (growth restriction) and are compounded by accelerated growth in early infancy.

    Full Text Available Introduction: Oxygen therapy used for preterm infant disease might be associated with oxygen toxicity or oxidative stress. The exact oxygen concentration to control and maintain the arterial oxygen saturation balance is not certainly clear. We aimed to compare the efficacy of higher or lower oxygen saturations on the development of severe retinopathy of prematurity which is a major cause of blindness in preterm neonates. Methods: PubMed was searched for obtaining the relevant articles. A total of seven articles were included after studying the titles, abstracts, and the full text of retrieved articles at initial search. Inclusion criteria were all the English language human clinical randomized controlled trials with no time limitation, which studied the efficacy of low versus high oxygen saturation measured by pulse oximetry in preterm infants.Result: It can be suggested that lower limits of oxygen saturations have higher efficacy at postmesetural age of ≤28 weeks in preterm neonates. This relation has been demonstrated in five large clinical trials including three Boost trials, COT, and Support.Discussion: Applying higher concentrations of oxygen supplementations at mesentural age ≥32 weeks reduced the development of retinopathy of prematurity. Lower concentrations of oxygen saturation decreased the incidence and the development of retinopathy of prematurity in preterm neonates while applied soon after the birth.Conclusions: Targeting levels of oxygen saturation in the low or high range should be performed cautiously with attention to the postmesentural age in preterm infants at the time of starting the procedures.

    Full Text Available During pregnancy, different froms of periodontal disease such as pregnancy gingivitis, pregnancy tumors, pregnancy stomatitis, may be encountered. But the most considerable point is the pregnant women's infection with periodontal disease and its effect on delivery and weight of newborn infants. Based on the latest researches and statistics, it is concluded that periodontal disease is an important risk factor, leading to preterm or premature delivery. On the other hand, poor hygiene, should be considered as another danger, resulting in premature delivery. Besides, the presence of a collection of oral fosobacteria in ammoniutic fluid in mothers with premature delivery, increases the probability of an oral- haematogenous connection. Moreover, prostaglandin E2, in cervicular fluid, has been considered as an index for periodontal disease activity and loss of weight at the time of birth. These findings suggest that effective steps, to prevent preterm delivery, can be taken, if women, genycologists and dentists have enough knowledge. This article focuses on the special supervision that is required to prevent the effects of hormonal changes on periodontal tissues and conversely to reduce systemic disorders resulting from periodontal disease, in pregnant woman.

    Several techniques have been reported to address different endovascular device failures. We report the case of a premature deployment of a covered balloon mounted stent during endovascular repair of a posttraumatic carotid-cavernous fistula(CCF). A 50-year-old male suffered a fall resulting in loss of consciousness and multiple facial fractures. Five weeks later, he developed decreased left visual acuity, proptosis, chemosis, limited eye movements and cranial/orbit bruit. Cerebral angiography demonstrated a direct left CCF and endovascular repair with a 5.0 mm × 19 mm covered stent was planned. Once in the lacerum segment, increased resistance was encountered and the stent was withdrawn resulting in premature deployment. A 3 mm × 9 mm balloon was advanced over an exchange length microwire and through the stent lumen. Once distal to the stent, the balloon was inflated and slowly pulled back in contact with the stent. All devices were successfully withdrawn as a unit. The use of a balloon to retrieve a prematurely deployed balloon mounted stent is a potential rescue option if leaving the stent in situ carries risks.

    Carnitine plays a significant role in fatty acid utilization and ketone body production. Its availability is especially important during the immediate postnatal period. To determine whether low birth weight infants who cannot be orally fed are at risk of developing carnitine deficiency, we compared the carnitine blood levels and urinary excretion of 12 premature infants (Group A) receiving total parenteral nutrition (TPN) with those of 8 infants of similar gestational age and birth weight (Group B) who received carnitine-containing milk formulas. In Group A, serum levels of total and free carnitine fell after 5 days of carnitine-deficient parenteral nutrition, and urinary excretion was significantly reduced. Serum levels and urinary excretion increased after the onset of oral feedings. The control Group B exhibited no significant changes in carnitine blood levels between the first and fifth days of life, but did show a later increase. Children in Group A had lower carnitine blood levels compared to those in Group B on the fifth day of life. These findings suggest that premature infants are not able to synthesize enough carnitine to maintain blood levels, and that carnitine deficiency can occur following TPN. Further investigation of metabolic consequences secondary to deficient carnitine intake in premature infants is necessary before carnitine supplementation should be considered.

    A well-organized interplay between many molecular factors as well as mechanical forces influence fetal lung development. At the end of this complex process a sufficiently sized and structurally mature organ should ensure the postnatal survival of the newborn. Besides prenatal ultrasonography, magnetic resonance imaging (MRI) can now be used to investigate normal and pathological human lung growth in utero. Oligohydramnios, due to premature rupture of membranes (PROM), is an important risk factor for compromised fetal lung growth. In these situations MR volumetry can be used to measure the size of the fetal lung quite accurately. Together with the evaluation of lung signal intensities on T2-weighted sequences, fetuses with pulmonary hypoplasia can be readily detected. (orig.) [German] Die fetale Lungenentwicklung wird einerseits durch eine Vielzahl molekularer Faktoren und andererseits durch mechanisch-physiologische Kraefte beeinflusst. Ein geordnetes Zusammenspiel dieser Mechanismen fuehrt zu einem ausreichend grossen und strukturell reifen Organ, das sofort nach der Geburt das Ueberleben des Neugeborenen sicherstellt. Neben der praenatalen Ultraschalluntersuchung bietet nun auch die Magnetresonanztomographie (MRT) die Moeglichkeit, die normale und pathologische fetale Lungenentwicklung zu untersuchen. Ein wesentlicher Risikofaktor fuer eine Beeintraechtigung der Lungenentwicklung ist die verminderte Fruchtwassermenge nach vorzeitigem Blasensprung. In diesen Faellen kann die MR-Volumetrie dazu eingesetzt werden, die Groesse der fetalen Lungen relativ genau zu bestimmen. Gemeinsam mit der Beurteilung der MR-Signalintensitaeten des Lungengewebes auf T2-gewichteten Sequenzen koennen Feten mit hypoplastischen Lungen mit zunehmender Sicherheit bereits praenatal identifiziert werden.

    Jill L Maron

    Full Text Available BACKGROUND: The current practice in newborn medicine is to subjectively assess when a premature infant is ready to feed by mouth. When the assessment is inaccurate, the resulting feeding morbidities may be significant, resulting in long-term health consequences and millions of health care dollars annually. We hypothesized that the developmental maturation of hypothalamic regulation of feeding behavior is a predictor of successful oral feeding in the premature infant. To test this hypothesis, we analyzed the gene expression of neuropeptide Y2 receptor (NPY2R, a known hypothalamic regulator of feeding behavior, in neonatal saliva to determine its role as a biomarker in predicting oral feeding success in the neonate. METHODOLOGY/PRINCIPAL FINDINGS: Salivary samples (n = 116, were prospectively collected from 63 preterm and 13 term neonates (post-conceptual age (PCA 26 4/7 to 41 4/7 weeks from five predefined feeding stages. Expression of NPY2R in neonatal saliva was determined by multiplex RT-qPCR amplification. Expression results were retrospectively correlated with feeding status at time of sample collection. Statistical analysis revealed that expression of NPY2R had a 95% positive predictive value for feeding immaturity. NPY2R expression statistically significantly decreased with advancing PCA (Wilcoxon test p value<0.01, and was associated with feeding status (chi square p value  =  0.013. CONCLUSIONS/SIGNIFICANCE: Developmental maturation of hypothalamic regulation of feeding behavior is an essential component of oral feeding success in the newborn. NPY2R expression in neonatal saliva is predictive of an immature feeding pattern. It is a clinically relevant biomarker that may be monitored in saliva to improve clinical care and reduce significant feeding-associated morbidities that affect the premature neonate.

    Based on the global predictions majority of deaths will be collectively caused by cancer, cardiovascular diseases, and traffic accidents over the coming 25 years. In planning future national health policy actions, inter - regional assessments play an important role. The purpose of the study was to analyze similarities and differences in premature mortality between Serbia, EURO A, EURO B, and EURO C regions in 2000. Mortality and premature mortality patterns were analysed according to cause of death, by gender and seven age intervals. The study results are presented in relative (%) and absolute terms (age-specific and age-standardized death rates per 100,000 population, and age-standardized rates of years of life lost - YLL per 1,000). Direct standardization of rates was undertaken using the standard population of Europe. The inter-regional comparison was based on a calculation of differences in YLL structures and with a ratio of age-standardized YLL rates per 1,000. A multivariate generalized linear model was used to explore mortality of Serbia and Europe sub-regions with ln age-specific death rates. The dissimilarity was achieved with a p death case. YLL patterns indicated similarities between Serbia and EURO A, while SRR YLL had similarities between Serbia and EURO B. Compared to all Europe sub-regions, Serbia had a major excess of premature mortality in neoplasms and diabetes mellitus. Serbia had lost more years of life than EURO A due to cardiovascular, genitourinary diseases, and intentional injuries. Yet, Serbia was not as burdened with communicable diseases and injuries as were EURO B and EURO C. With a premature mortality pattern, Serbia is placed in the middle position of the Europe triangle. The main excess of YLL in Serbia was due to cardiovascular, malignant diseases, and diabetes mellitus. The results may be used for assessment of unacceptable social risks resulting from health inequalities. Within intentions to reduce an unfavourable premature

    Full Text Available Background Patent ductus arteriosus (PDA is a congenital heart disease most commonly occurring in premature infants. Spontaneous ductus arteriosus (DA closure in premature infants has been suggested to be associated with duct lumen maturity and the DA sensitivity to prostaglandin E2 (PGE2. Objective To assess for a possible correlation between serum PGE2 levels and PDA size in premature infants. Methods This observational study using repeated measurements on premature infants with PDA detected at days 2-3 of life was undertaken in Cipto Mangunkusumo Hospital and Fatmawati Hospital, Jakarta, from April to May 2014. The PDA was diagnosed using 2-D echocardiography and PGE2 levels were measured by immunoassay. Pearson’s correlation test was used to evaluate a possible correlation between PGE2 level and DA diameter. Results Thirty-three premature infants of median gestational age 31 (range 28-32 weeks and median birth weight 1,360 (range 1,000-1,500 grams were enrolled. Almost two-thirds of the subjects were male. Almost all (30/33 subjects had spontaneous DA closure before the age of 10 days. Subjects’ mean DA diameter was 2.9 (SD 0.5 mm with maximum flow velocity of 0.2 (SD 0.06 cm/sec, and left atrial-to-aortic root ratio (LA/Ao of 1.5 (SD 0.2. Their mean PGE2 levels at the ages of 2-3, 5-7, and after 10 days were 5,238.6 (SD 1,225.2, 4,178.2 (SD 1,534.5, and 915.2 (SD 151.6 pg/mL, respectively. The PGE2 level at days 2-3 was significantly correlated with DA diameter (r = 0.667; P < 0.001, but not at days 5-7 (r = 0.292; P = 0.105 or at day 10 (r = 0.041; P = 0.941. Conclusion There is a strong, positive correlation between the PGE2 level and DA diameter in preterm infants at 2-3 days of age. However, there is no significant correlation between PGE2 level and persistence of PDA.

    Background Glutamine, proposed to be conditionally essential for critically ill patients, is not added routinely to parenteral amino acid formulations for premature infants and is provided in only small quantities by the enteral route when enteral feeding is Iow. Parenteral feeding is the basic way of nutrition in the first days of life of premature infants. In this study, we evaluated the effects of glutamine supplemented parenteral nutrition for premature infants on growth and development, feeding toleration, and infective episodes.Methods From December 2002 to July 2006, 53 premature infants were given either standard or glutamine supplemented parenteral nutrition for more than 2 weeks. Twenty-eight infants were in glutamine supplemented group, whose gestational age (31.4±2.0) weeks, birth weight range (1386±251) g; twenty-five infants were in control group, gestational age (31.1 ± 1.7) weeks, with birth weight range (1346± 199) g. There were no differences between the two groups. Various growth and biochemical indices were monitored throughout the duration of hospital stay. Data between groups were analyzed with Student's t test. Nonparametric data were analyzed using a Chi-square test. A two-tailed P value < 0.05 was considered statistically significant.Results The level of serum albumin was lower in the glutamine groups on the second week (3.0 vs 3.2 g/dl, P=0.028), and blood urea nitrogen was higher in glutamine groups on the fourth week (8.1 vs 4.9 mg/dl, P=0.014), but normal. Glutamine group infants took fewer days to regain birth weight (8.1 vs 10.4 days, P=0.017), required fewer days on parenteral nutrition (24.8 vs 30.8 days, P=0.035), with shorter stays in hospital (32.1 vs 38.6 days, P=0.047). Episodes of hospital acquired infection in glutamine supplemented infants were lower than that in control group (0.96 vs 1.84 times, P=0.000).Conclusion Parenteral glutamine supplementation in premature infants can shorten days on parenteral nutrition and

    Premature ejaculation (PE) is a common male sexual dysfunction that can have significant effects on a couple's relationship. Behavioral therapy and psychotherapy are both safe and effective methods of treating PE. Ancient Chinese fangzhongshu (sexual skills and methods), which reflects a summary of expert experiences in sexology, contains many therapies for sexual dysfunction that are similar to those used in behavioral therapy or psychotherapy. A brief introduction dealing with the latest definitions of PE and treatment strategies drawn from behavioral therapy and psychotherapy is provided. Typical therapies for PE from ancient Chinese fangzhongshu are listed and briefly analyzed in order to define their domain of applicability and instructions for use. Ancient Chinese fangzhongshu contains many effective and safe therapies for PE. It should be incorporated into modern medical practice after critical analysis, and its scientific aspects should be promoted as a way of improving reproductive health, both to benefit individuals affected by PE and to promote traditional Chinese culture. Based on an analysis of the condition of the individual patient, one or multiple therapies guided by fangzhongshu can be expected to have an effect on the patient. Ancient Chinese fangzhongshu is of great value and should to be popularized and applied as a remedy for PE. PMID:28053946

    Full Text Available Background. In premature infants, maintaining blood partial pressure of carbon dioxide (pCO2 value within a narrow range is important to avoid cerebral lesions. The aim of this study was to assess the accuracy of a noninvasive transcutaneous method (TcpCO2, compared to blood partial pressure of carbon dioxide (pCO2. Methods. Retrospective observational study in a tertiary neonatal intensive care unit. We analyzed the correlation between blood pCO2 and transcutaneous values and the accuracy between the trends of blood pCO2 and TcpCO2 in all consecutive premature infants born at <33 weeks’ gestational age. Results. 248 infants were included (median gestational age: 29 + 5 weeks and median birth weight: 1250 g, providing 1365 pairs of TcpCO2 and blood pCO2 values. Pearson’s R correlation between these values was 0.58. The mean bias was −0.93 kPa with a 95% confidence limit of agreement of −4.05 to +2.16 kPa. Correlation between the trends of TcpCO2 and blood pCO2 values was good in only 39.6%. Conclusions. In premature infants, TcpCO2 was poorly correlated to blood pCO2, with a wide limit of agreement. Furthermore, concordance between trends was equally low. We warn about clinical decision-making on TcpCO2 alone when used as continuous monitoring.

    2017-05-01

    Full Text Available Background: The appropriate moment for clamping the umbilical cord is controversial. Immediate cord clamping (ICC is an item of active management of the third stage of labor (AMTSL. Unclamped umbilical cord may cause inconvenience in preterm neonates because they commonly need some levels of emergent services. Some studies revealed delayed cord clamping (DCC of preterm neonates results in better health conditions like lower rates of respiratory distress syndrome (RDS, less morbidities in labor room and lower risk of postpartum hemorrhage. The aim of the present study was to determine the effect of delayed umbilical cord clamping on premature neonatal outcomes. Materials and Methods: In this single‑center randomized control trial study, sixty premature neonates (gestational age ≤ 34 weeks were randomly assigned to ICC (cord clamped at 5–10 seconds or DCC (30–45 seconds groups and followed up in neonatal intensive care unit (NICU. Primary outcomes were 1st and 5th minute Apgar score, average of level of hematocrit after birth, intra ventricle hemorrhage and need some levels of resuscitation. Results: Differences in demographic characteristics were not statistically significant. After birth, neonates who had delayed clamping had significantly higher mean hematocrit after at 4-hour of birth (49.58+5.15gr/dl vs. 46.58+5.40gr/dlin DCC vs. ICC groups, respectively (P=0.031. Delayed cord clamping reduced the duration of need to nasal continues positive airway pressure (NCPAP (86.7% and 60.0% in ICC and DCC groups, respectively, P= 0.039. Attractively, the results showed lower incidence of clinical sepsis in delayed cord clamping neonates (53.3% vs. 23.3% in ICC and DCC groups, respectively, P=0.033. Conclusion: Prematurity complications might decrease by delay umbilical cord clamping which improve the hematocrit, duration of need to NCPAP and incidence of clinical sepsis. Furthermore, DCC may have no negative impact on neonatal resuscitation.

    A significant increase of the elderly in populations of developed countries is followed by increase morbidity and mortality from main age-related diseases--cardiovascular and neuro-degenerative, cancer, diabetes mellitus, declining in a resistance to infections. Obviously, the development of means of the prevention of the premature ageing and these diseases in humans are crucial at present. However, data on such type means rather scarce, contradictory and often not reliable from the points of view of the adequacy of the experiments to current scientific requirements, as well as the interpretation of the results and safety. Available data on the life span extension and adverse effects of chemical compounds and drugs suggested as geroprotectors are critically analyzed: antidiabetic drugs, growth and thyroid hormones, glucocorticoids, DHEA, sex steroids and contraceptives, melatonin and peptide preparations modulating the pineal gland, antioxidants, chelate agents and lathyrogens, adaptogens and herbs, neurotropic drugs, inhibitors of monoamine oxidase, immunomodulators and some other. Most of the results could not convincingly evidence the life span extension and safety of the suggested geroprotectors. We believe that it is necessary to establish an international program for the expert evaluation of the life span extension potential of pharmacological interventions for humans. The scope of the program should be to evaluate chemical, immunological, dietary and behavioural interventions that may lead to life span extension or retard premature ageing and the objective--preparation of critical reviews and evaluations on evidence of the life span extending properties of a wide range of potential geroprotectors and strategies by international groups of working experts. The program may assist national and international authorities in devising programs of health promotion and premature ageing prevention.

    2002-06-01

    Premature ovarian failure (POF) is a unique example of isolated organ senescence, with a population prevalence of approximately 1%. Though the phenotypic expression of POF is similar to that of age-appropriate natural menopause, the underlying pathophysiological mechanisms are diverse and not entirely clear. The impact of POF on the patient is profound, with myriad ramifications, ranging from psychological devastation to multi-system implications of estrogen deprivation and its sequelae. The hastening of degenerative changes noted in these patients however, are not entirely ameliorated with estrogen replacement and POF may indeed represent an acceleration of the aging process.

    To determine the dynamic morphologic development of the human fovea in vivo using portable spectral domain-optical coherence tomography (SD-OCT). Prospective, observational case series. Thirty-one prematurely born neonates, 9 children, and 9 adults. Sixty-two neonates were enrolled in this study. After examination for retinopathy of prematurity (ROP), SD-OCT imaging was performed at the bedside in nonsedated infants aged 31 to 41 weeks postmenstrual age (PMA) (= gestational age in weeks + chronologic age) and at outpatient follow-up ophthalmic examinations. Thirty-one neonates met eligibility criteria. Nine children and nine adults without ocular pathology served as control groups. Semiautomatic retinal layer segmentation was performed. Central foveal thickness, foveal to parafoveal (FP) ratio (central foveal thickness divided by thickness 1000 μm from the foveal center), and 3-dimensional thickness maps were analyzed. In vivo determination of foveal morphology, layer segmentation, analysis of subcellular changes, and spatiotemporal layer shifting. In contrast with the adult fovea, several signs of immaturity were observed in the neonates: a shallow foveal pit, persistence of inner retinal layers (IRLs), and a thin photoreceptor layer (PRL) that was thinnest at the foveal center. Three-dimensional mapping showed displacement of retinal layers out of the foveal center as the fovea matured and the progressive formation of the inner/outer segment band in the opposite direction. The FP-IRL ratios decreased as IRL migrated before term and minimally after that, whereas FP-PRL ratios increased as PRL subcellular elements formed closer to term and into childhood. A surprising finding was the presence of cystoid macular edema in 58% of premature neonates that appeared to affect inner foveal maturation. This study provides the first view into the development of living cellular layers of the human retina and of subcellular specialization at the fovea in premature infant eyes

    The aim of this article is to examine the effect of omega-3 (ω-3) long-chain polyunsaturated fatty acids (LCPUFAs) intake on retinopathy of prematurity (ROP) by reviewing the experimental and clinical trials conducted on animal models and infants. LCPUFAs demonstrate cytoprotective and cytotherapeutic actions contributing to a number of anti-angiogenic and neuroprotective mechanisms within the retina. Their intake appears to have a beneficial effect on ischemia, oxidative stress, inflammation and cellular signaling mechanisms, influencing retinal cell gene expression and cellular differentiation. ω-3 LCPUFAs may modulate metabolic processes that activate molecules implicated in the pathogenesis of vasoproliferative and neurodegenerative retinal diseases such as ROP.

    The recently developed technique of gas chromatography-mass spectrometry supported by computer has considerably improved the analysis of physiologic fluids. This study attempted to demonstrate the value of this system in the investigation of metabolite patterns in urine in two metabolic problems of prematurity, transient tyrosinemia and late metabolic acidosis. Serial 24-hr urine specimens were analyzed in 9 infants. Transient tyrosinemia, characterized by 5- 10-fold increases over basal excretion of tyrosine, p-hydroxyphenyllactate, and p-hydroxyphenylpyruvate in urine, was noted in five of the infants. Late metabolic acidosis was seen in four infants, but bore no relation to transient tyrosinemia.

    Bovine mastitis is an economic and a welfare problem on dairy farms. The objective of this study was to estimate the costs of clinical mastitis (CM), having a special focus on the cost variation related to culling decisions. A dynamic optimization model was developed to determine an optimal replacement time of a mastitic cow and to estimate the costs of CM, taking into account the risk of premature culling and the uncertainty in CM prevalence. Six lactations were analyzed at monthly periods for Ayrshire and Holstein-Friesian breeds. The estimates reflect Finnish production conditions where mastitis is treated only by veterinarians. Biological parameters of the model were adapted from the literature and the Finnish dairy herd health recording system. Field data were used to produce the risk parameters of culling due to mastitis on commercial dairy farms. The model recommended treating the cows with CM and keeping them in most cases until their fifth lactation. A cheaper (-20%) heifer transferred the optimum to the previous lactation and a more expensive (+20%) heifer to the following lactation. Conditional on optimal replacements, the average cost of CM of an Ayrshire (Holstein-Friesian costs in parentheses) cow was €485 (€458), varying from €209 (€112) to €1,006 (€946). The costs were at the highest when the occurrence of CM was at a top yield phase. In the scenario where the risk of culling due to mastitis was included in the model, the average cost of CM was €596 (€623). Disposing of a young cow at the end of her first lactation month caused the highest costs. The costs converted to figures per cow-year were €121 (€147) with optimal cullings and €155 (€191) in the current Finnish conditions. Thus, the increase in the costs of CM due to premature cullings was 28% (30%.) The main cost sources were long-term production losses regardless of the culling decisions. Premature culling formed 20% (23%) of the total costs. To decrease the costs of

    In this paper, the author revisits the problem of 'premature ego development' first introduced by Melanie Klein in 1930. She also highlights several developments in post-Kleinian thinking since the publication of that paper, which can be seen as offshoots of or complements to Klein's work. The author proposes a link between this category of precocious development and the absence of the experience of what Bion termed the 'containing object.' She puts forward several technical considerations relevant to analytic work with patients who suffer as a result of early developmental failures and presents various clinical vignettes in order to demonstrate the ways in which these considerations take shape in the analytic setting.

    Testosterone (T) deficiency remains a poorly understood issue in men with Human Immunodeficiency Virus (HIV). We investigated the gonadal status in HIV-infected men in order to characterize T deficiency and to identify predictive factors for low serum T. We performed a cross-sectional, observational study on 1325 consecutive HIV male outpatients, most of them having lipodystrophy. Serum total Tcase. Sexual behavior was evaluated in a subset of 247 patients. T deficiency was found in 212 subjects, especially in the age range 40-59, but was frequent even in younger patients. T deficiency occurred mainly in association with low/normal serum LH. Adiposity was higher in subjects with T deficiency (p<0.0001) and both visceral adipose tissue and body mass index were the main negative predictors of serum total T. Osteoporosis and erectile dysfunction were present in a similar percentage in men with or without T deficiency. Premature decline of serum T is common (16%) among young/middle-aged HIV-infected men and is associated with inappropriately low/normal LH and increased visceral fat. T deficiency occurs at a young age and may be considered an element of the process of premature or accelerated aging known to be associated with HIV infection. The role of HIV and/or HIV infection treatments, as well as the role of the general health state on the gonadal axis, remains, in fact, to be elucidated. Due to the low specificity of signs and symptoms of hypogonadism in the context of HIV, caution is needed in the diagnosis of hypogonadism in HIV-infected men with biochemical low serum T levels.

    Full Text Available McCarty EJ, Dinsmore WWDepartment of Genitourinary Medicine, Royal Victoria Hospital, Belfast, IrelandAbstract: Premature ejaculation (PE is a major issue in male sexual health. The global prevalence of PE is estimated to be between 20% and 40%, making it the most common sexual dysfunction in men. PE causes distress and reduced quality of life for patients and has a negative impact on interpersonal relationships. Historically, it has been treated with cognitive therapy, behavioral methods, and off-label use of selective serotonin reuptake inhibitors usually used to treat depression and other psychological disorders. Dapoxetine is a selective serotonin reuptake inhibitor specifically designed to treat PE. This paper reviews the current evidence for use of dapoxetine in the treatment of PE in adult men. There is substantial evidence that dapoxetine 30 mg or 60 mg taken “on-demand” results in a significant increase in intravaginal ejaculatory latency time when compared with placebo. Patient-reported outcomes are clearly improved relative to placebo following dapoxetine therapy, indicating greater control over ejaculation, more satisfaction with intercourse, less ejaculation-related distress, and, importantly, significantly reduced interpersonal difficulty. These data were supported by consistent reports of improvement in Clinical Global Impression of change in PE following treatment with dapoxetine. Further studies are needed to evaluate long-term efficacy and health economics. The unique pharmacology of dapoxetine makes it ideal for on-demand dosing, and the clinical evidence shows dapoxetine to be an efficacious and tolerable treatment for lifelong and acquired PE.Keywords: dapoxetine, intravaginal ejaculatory latency time, patient-reported outcomes, premature ejaculation

    Full Text Available The objectives of this study were to comprehend the breastfeeding process from reports of mothers of premature babies and identify factors facilitating or complicating this process. A descriptive qualitative study regarding the family centered care. We conducted 12 interviews with mothers of six months premature babies of chronological age and we submitted data to content analysis. Four categories emerged: The previous breastfeeding experience in the process of breastfeeding the premature baby; Emotional context versus the breastfeeding process; The ability to manage breastfeeding the premature baby and, Successes and failures. We concluded that family and professional support, adequate management and the welcoming of individualized services in the prematurity context were majorly responsible for the breastfeeding success, being even able to surpass the previous maternal desire. Breastfeeding accompaniment after discharge is indispensable for its success with premature babies.

    To determine the birth prevalence of congenital heart defects (CHDs) across the spectrum of common defects in very/extremely premature infants and to compare mortality rates between premature infants with and without CHDs. The Kids' Inpatient Databases (2003-2012) were used to estimate the birth prevalence of CHDs (excluding patent ductus arteriosus) in very/extremely premature infants born between 25 and 32 weeks' gestational age. Birth prevalence was compared with term infants for a subset of "severe" defects expected to be near universally diagnosed in the neonatal period. Weighted multivariable logistic regression was used to calculate aORs of mortality comparing very and extremely premature infants with vs without CHDs. We identified 249 011 very/extremely premature infants, including 28 806 with CHDs. The overall birth prevalence of CHDs was 116 per 1000 very/extremely premature births. Severe CHDs had significantly higher birth prevalence in very/extremely premature infants when compared with term infants (7.4 per 1000 very/premature births vs 1.5 per 1000 term births; P premature infants with severe CHDs had an overall 26.3% in-hospital mortality and a 7.5-fold increased adjusted odds of death compared with those without CHDs. Mortality varied widely by defect in very/extremely premature infants, ranging from 12% for interrupted aortic arch to 67% for truncus arteriosus. Given the increased birth prevalence of severe CHDs in very/extremely premature infants, and significantly higher mortality, there is justification for intensive interventions aimed at decreasing the likelihood of premature delivery for patients where CHD is diagnosed in utero.

    Full Text Available ABSTRACTPurpose:To investigate the influence of the blood glucose level on the development of retinopathy of prematurity (ROP in extremely premature infants.Methods:Sixty-four premature infants with a gestational age of less than 30 weeks and a birth weight of less than 1500 g were included in the study. Children without ROP were allocated to Group 1 (n=14, gestational age 28.6 ± 1.4 weeks, birth weight 1162 ± 322 g, and children with spontaneous regression of ROP were allocated to Group 2 (n=32, gestational age 26.5 ± 1.2 weeks, birth weight 905 ± 224 g. Children with progressive ROP who underwent laser treatment were included in Group 3 (n=18, gestational age 25.4 ± 0.7 weeks, birth weight 763 ± 138 g. The glucose level in the capillary blood of the premature infants was monitored daily during the first 3 weeks of life. A complete ophthalmological screening was performed from the age of 1 month. The nonparametric signed-rank Wilcoxon-Mann-Whitney test was used for statistical analysis.Results:The mean blood glucose level was 7.43 ± 2.6 mmol/L in Group 1, 7.8 ± 2.7 mmol/L in Group 2, and 6.7 ± 2.6 mmol/L in Group 3. There were no significant differences in the blood glucose levels between children with and without ROP, and also between children with spontaneously regressing ROP and progressive ROP (p>0.05. Additionally, there were no significant differences in the blood glucose levels measured at the first, second, and third weeks of life (p>0.05.Conclusion:The blood glucose level is not related to the development of ROP nor with its progression or regression. The glycemic level cannot be considered as a risk factor for ROP, but reflects the severity of newborns’ somatic condition and morphofunctional immaturity.

    Events causing stress responses during sensitive periods of rapid neurological development in childhood may be early determinants of all-cause premature mortality. Using a British birth cohort study of individuals born in 1958, the relationship between adverse childhood experiences (ACE) and mortality≤50 year was examined for men (n=7,816) and women (n=7,405) separately. ACE were measured using prospectively collected reports from parents and the school: no adversities (70%); one adversity (22%), two or more adversities (8%). A Cox regression model was carried out controlling for early life variables and for characteristics at 23 years. In men the risk of death was 57% higher among those who had experienced 2+ ACE compared to those with none (HR 1.57, 95% CI 1.13, 2.18, p=0.007). In women, a graded relationship was observed between ACE and mortality, the risk increasing as ACE accumulated. Women with one ACE had a 66% increased risk of death (HR 1.66, 95% CI 1.19, 2.33, p=0.003) and those with ≥2 ACE had an 80% increased risk (HR 1.80, 95% CI 1.10, 2.95, p=0.020) versus those with no ACE. Given the small impact of adult life style factors on the association between ACE and premature mortality, biological embedding during sensitive periods in early development is a plausible explanatory mechanism.

    Inhibin is an important glycoprotein that is involved in folliculogenesis. INHA, the gene encoding the inhibin alpha subunit, was recently proposed as a candidate for premature ovarian failure (POF), a syndrome that leads to the cessation of ovarian function under the age of 40 years. 70 POF patients and 70 controls were screened for the previously identified INHA -16C>T transition mutation. The T allele was found in 31/70 (44.3%) of controls, but only 18/70 (25.7%) of POF patients. This result indicates that the T allele is significantly underrepresented in the POF patient population (Fisher's exact test, two-tail: P = 0.033). Sequence analysis of the INHA promoter in 50 POF patients and 50 controls identified a highly polymorphic imperfect TG repeat at approximately -300 bp, that consisted of four common haplotypes (A, B, C and D). The -16T allele is linked to the shortest repeat haplotype (haplotype C). Despite the association between haplotype C and POF, no significant difference was found between the promoter activity of a luciferase reporter construct containing haplotype C, and most of the other haplotypes tested. Interestingly, haplotype B failed to show any promoter activity. We conclude that the inheritance of specific INHA promoter haplotypes predispose to the development of premature ovarian failure.

    Full Text Available Background: Prematurity is the most common cause of death and disability And Preterm infants, are prone to developmental complications. For this reason this study was designed for follow up of these babies until 2 years by modified DDST-2. Methods: This study was a prospective longitudinal descriptive study from March 2009 to March 2011 in clinic of sheikh and Imam Reza Hospitals, mashhad, Iran. Sample size with Confidence coefficient of 95% and power 80%, was determined 100 hundred babies. Infants were seen by a pediatrician at a follow up clinic at 1, 3, 6, 9,12,15,18, 24, months.The developmental assessment was done using Denver-2 Developmental Screening Test. Results: mean age for smiling was 4/6 ± 2/1  months which significantly differed with appropriate age (p = 0.000, mean age for telling two syllables words 11/7±  1/9 months, without significant difference of appropriate age.(p = 0.139. Average age for understanding NO was 10/4±  2/0 months that significantly differed with appropriate age(p = 0.000. The average age for telling 6 word was 17/8±  3/0, without significant difference with appropriate age (p = 0.510. Conclusion: Children with history of prematurity and low birth weight have more disability and developmental delay so they need to developmental screening tests.

    Retinopathy of prematurity (ROP) is a disorder of blood vessels in the retina developed in premature infants and the leading cause of the blindness in children. Proteomic analysis was performed to identify vitreous proteins specific to patients with ROP. Vitreous humor samples were obtained from three patients with ROP and two patients with congenital cataract, the latter included as a control group. The vitreous samples were separated by 2D-PAGE and the proteins running as definitive spots were identified by MALDI-TOF MS spectrometry. We identified 13 and 6 proteins in the vitreous from ROP and cataract patients, respectively. Albumin, transferrin, pigment epithelium-derived factor (PEDF) and transthyretin were found in both patient groups. In the samples from ROP patients, PEDF and transthyretin levels were lower than in those from cataract patients, and retinol binding protein 3 and prostaglandin D synthase were not detected. Of the 13 proteins, 9 proteins including α-2-macroglobulin, ceruloplasmin, α-fetoprotein, vitamin D-binding protein, α-1-antitrypsin, α-1-β-glycoprotein, hemopexin, apolipoprotein A-1 and A-lV were found in vitreous samples of only the ROP patients. PEDF has anti-angiogenic and neurotrophic functions. Whether PEDF is increased or decreased in diabetic retinopathy has been controversial but we observed lower PEDF in the ROP samples than in the controls. The proteins specific to or decreased in ROP, if confirmed in future studies, may provide clue to understanding its pathogenesis. Copyright © 2017 Elsevier Inc. All rights reserved.

  13. Adolescent Premature Ovarian Insufficiency Following Human Papillomavirus Vaccination

    Directory of Open Access Journals (Sweden)

    Deirdre Therese Little MBBS, DRANZCOG, FACRRM

    2014-10-01

    Full Text Available Three young women who developed premature ovarian insufficiency following quadrivalent human papillomavirus (HPV vaccination presented to a general practitioner in rural New South Wales, Australia. The unrelated girls were aged 16, 16, and 18 years at diagnosis. Each had received HPV vaccinations prior to the onset of ovarian decline. Vaccinations had been administered in different regions of the state of New South Wales and the 3 girls lived in different towns in that state. Each had been prescribed the oral contraceptive pill to treat menstrual cycle abnormalities prior to investigation and diagnosis. Vaccine research does not present an ovary histology report of tested rats but does present a testicular histology report. Enduring ovarian capacity and duration of function following vaccination is unresearched in preclinical studies, clinical and postlicensure studies. Postmarketing surveillance does not accurately represent diagnoses in adverse event notifications and can neither represent unnotified cases nor compare incident statistics with vaccine course administration rates. The potential significance of a case series of adolescents with idiopathic premature ovarian insufficiency following HPV vaccination presenting to a general practice warrants further research. Preservation of reproductive health is a primary concern in the recipient target group. Since this group includes all prepubertal and pubertal young women, demonstration of ongoing, uncompromised safety for the ovary is urgently required. This matter needs to be resolved for the purposes of population health and public vaccine confidence.

    Objective To determine the frequency of cardiorespiratory events following routine exams for retinopathy of prematurity (ROP). Study Design This is a retrospective review of 79 premature infants in the neonatal intensive care unit at the University of Rochester Medical Center. The baseline for each infant (mean cardiorespiratory events in the 72 hours before the exam) was compared with the number of cardiorespiratory events during the subsequent 24 hours using generalized estimating equation and the Mantel-Haenszel chi-square test to determine if there was an association between cardiorespiratory events and potential risk factors. Results Approximately 19 to 25% of infants experienced an increase in cardiorespiratory events in the 24 hours following their eye exams. These newborns were generally of a younger gestational age and lower birthweight. Conclusion The frequency of cardiorespiratory events following routine ROP exams is similar to that following routine immunizations in this population. Thus, in infants being continuously monitored during the 24 hours after the exam, alterations in medical care in the absence of other clinical signs suggestive of sepsis or clinical deterioration may not be required, limiting unnecessary antibiotic exposure, prolonged caffeine administration, unwarranted gastroesophageal reflux treatment, and undue family stress.

    Preterm birth is the second leading cause of death in children under the age of five years worldwide, but the etiology of many cases remains enigmatic. The dogma that the fetus resides in a sterile environment is being challenged by recent findings and the question has arisen whether microbes that colonize the fetus may be related to preterm birth. It has been posited that meconium reflects the in-utero microbial environment. In this study, correlations between fetal intestinal bacteria from meconium and gestational age were examined in order to suggest underlying mechanisms that may contribute to preterm birth. Meconium from 52 infants ranging in gestational age from 23 to 41 weeks was collected, the DNA extracted, and 16S rRNA analysis performed. Resulting taxa of microbes were correlated to clinical variables and also compared to previous studies of amniotic fluid and other human microbiome niches. Increased detection of bacterial 16S rRNA in meconium of infants of premature birth. This provides the first evidence to support the hypothesis that the fetal intestinal microbiome derived from swallowed amniotic fluid may be involved in the inflammatory response that leads to premature birth.

    The retinopathy of prematurity (ROP) is a potentially avoidable cause of blindness in children. The advances in neonatal care make the survival of extremely premature infants, who show a greater incidence of the disease, possible. The aim of the study is to evaluate the reliability of ROP screening using retinography imaging with the RetCam 3 wide-angle camera and also study the variability of ROP diagnosis depending on the evaluator. The indirect ophthalmoscopy exam was performed by a Pediatric ROP-Expert Ophthalmologist. The same ophthalmologist and a technician specialized in digital image capture took retinal images using the RetCam 3 wide-angle camera. A total of 30 image sets were analyzed by 3 masked groups: group A (8 ophthalmologists), group B (5 experts in vision), and group C (2 ROP-expert ophthalmologists). According to the diagnosis using indirect ophthalmoscopy, the sensitivity (26-93), Kappa (0.24-0.80), and the percent agreement were statistically significant in group C for the diagnosis of ROP Type 1. In the diagnosis of ROP Type 1+Type 2, Kappa (0.17-0.33) and the percent agreement (58-90) were statistically significant, with higher values in group C. The diagnosis, carried out by ROP-expert ophthalmologists, using the wide-angle camera RetCam 3 has proved to be a reliable method. Copyright © 2013 Asociación Española de Pediatría.

Participants were classified into two groups [premature hair graying (PHG and normal hair graying]. PHG was defined as the first appearance of gray hair before the age of 30. Data were collected using an interview questionnaire and measurements of body mass index, waist circumference, fasting blood glucose and blood pressure. Collected data were statistically analyzed using SPSS 16, Chicago, IL. Results: Of the 207 subjects, 104 (50.2% had first appearance of gray hair before the age of 30 (PHG group while the other 103 (49.8% were considered normal hair graying group. The prevalence of smokers in the "PHG" group was higher (40.2% vs. 24.7%, P = 0.031. Smokers had earlier onset of hair graying (smokers: 31 (7.4 vs. nonsmokers: 34 (8.6, P = 0.034. Using multiple logistic regression with conditional likelihood, smokers were two and half times (95% CI: 1.5-4.6 more prone to develop PHG. Conclusion: This study suggests that there is a significant relation (with adjusted odds ratio of two and half between onset of gray hair before the age of 30 and cigarette smoking.
